* Add --disable-major-minor-libraries configure option fw/no-symlinksFlorian Weimer2019-11-281-1/+7
| | | | | | | | | | | | | | | | | | This option can be used to increase compatibility with package managers. The name was choosen to avoid confusion with all the different versions (glibc release, soname versions, symbol versions). This patch makes all uses of -$(version).so conditional on the new $(major-minor-libraries) flag. The alternative install targets write the implementation DSOs directly to the locations determined by their sonames, skipping the creation of an intermediate symbolic link. install-symbolic-link in Makerules is updated not to require the $(symbolic-link-list) file because it may not exist in --disable-major-minor-libraries mode. I verified that by default, the install tree is the same as before on x86_64-linux-gnu except for the changes in the manual.
* Move _dl_open_check to its original place in dl_open_workerFlorian Weimer2019-11-271-6/+2
| | | | | | | | | | | | This reverts the non-test change from commit d0093c5cefb7f7a4143f ("Call _dl_open_check after relocation [BZ #24259]"), given that the underlying bug has been fixed properly in commit 61b74477fa7f63 ("Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]"). Tested on x86-64-linux-gnu, with and without --enable-cet. Change-Id: I995a6cfb89f25d2b0cf5e606428c2a93eb48fc33
* Block signals during the initial part of dlopenFlorian Weimer2019-11-271-2/+26
| | | | | | | | | | | Lazy binding in a signal handler that interrupts a dlopen sees intermediate dynamic linker state. This has likely been always unsafe, but with the new pending NODELETE state, this is clearly incorrect. Other threads are excluded via the loader lock, but the current thread is not. Blocking signals until right before ELF constructors run is the safe thing to do. Change-Id: Iad079080ebe7442c13313ba11dc2797953faef35
* Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]Florian Weimer2019-11-279-38/+308
| | | | | | | | | | | | | This introduces a “pending NODELETE” state in the link map, which is flipped to the persistent NODELETE state late in dlopen, via activate_nodelete. During initial relocation, symbol binding records pending NODELETE state only. dlclose ignores pending NODELETE state. Taken together, this results that a partially completed dlopen is rolled back completely because new NODELETE mappings are unloaded. Tested on x86_64-linux-gnu and i386-linux-gnu.

* Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]Florian Weimer2019-11-273-129/+249
| | | | | | | | | | | | | | | | | | | | | | | | This change splits the scope and TLS slotinfo updates in dlopen into two parts: one to resize the data structures, and one to actually apply the update. The call to add_to_global_resize in dl_open_worker is moved before the demarcation point at which no further memory allocations are allowed. _dl_add_to_slotinfo is adjusted to make the list update optional. There is some optimization possibility here because we could grow the slotinfo list of arrays in a single call, one the largest TLS modid is known. This commit does not fix the fatal meory allocation failure in _dl_update_slotinfo. Ideally, this error during dlopen should be recoverable. The update order of scopes and TLS data structures is retained, although it appears to be more correct to fully initialize TLS first, and then expose symbols in the newly loaded objects via the scope update. Tested on x86_64-linux-gnu. Change-Id: I240c58387dabda3ca1bcab48b02115175fa83d6c
* Avoid late failure in dlopen in global scope update [BZ #25112]Florian Weimer2019-11-271-48/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | The call to add_to_global in dl_open_worker happens after running ELF constructors for new objects. At this point, proper recovery from malloc failure would be quite complicated: We would have to run the ELF destructors and close all opened objects, something that we currently do not do. Instead, this change splits add_to_global into two phases, add_to_global_resize (which can raise an exception, called before ELF constructors run), and add_to_global_update (which cannot, called after ELF constructors). A complication arises due to recursive dlopen: After the inner dlopen consumes some space, the pre-allocation in the outer dlopen may no longer be sufficient. A new member in the namespace structure, _ns_global_scope_pending_adds keeps track of the maximum number of objects that need to be added to the global scope. This enables the inner add_to_global_resize call to take into account the needs of an outer dlopen. Most code in the dynamic linker assumes that the number of global scope entries fits into an unsigned int (matching the r_nlist member of struct r_scop_elem). Therefore, change the type of _ns_global_scope_alloc to unsigned int (from size_t), and add overflow checks. Change-Id: Ie08e2f318510d5a6a4bcb1c315f46791b5b77524
* Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304]Florian Weimer2019-11-276-21/+210
| | | | | | | | | | | | | | | | | | | | | If a lazy binding failure happens during the execution of an ELF constructor or destructor, the dynamic loader catches the error and reports it using the dlerror mechanism. This is undesirable because there could be other constructors and destructors that need processing (which are skipped), and the process is in an inconsistent state at this point. Therefore, we have to issue a fatal dynamic loader error error and terminate the process. Note that the _dl_catch_exception in _dl_open is just an inner catch, to roll back some state locally. If called from dlopen, there is still an outer catch, which is why calling _dl_init via call_dl_init and a no-exception is required and cannot be avoiding by moving the _dl_init call directly into _dl_open. _dl_fini does not need changes because it does not install an error handler, so errors are already fatal there.

* dlsym: Do not determine caller link map if not neededFlorian Weimer2019-11-271-4/+21
| | | | | | | | | | | | | | | | Obtaining the link map is potentially very slow because it requires iterating over all loaded objects in the current implementation. If the caller supplied an explicit handle (i.e., not one of the RTLD_* constants), the dlsym implementation does not need the identity of the caller (except in the special case of auditing), so this change avoids computing it in that case. Even in the minimal case (dlsym called from a main program linked with -dl), this shows a small speedup, perhaps around five percent. The performance improvement can be arbitrarily large in principle (if _dl_find_dso_for_object has to iterate over many link maps). Change-Id: Ide5d9e2cc7ac25a0ffae8fb4c26def0c898efa29
* Compile elf/rtld.c with -fno-tree-loop-distribute-patterns.Sandra Loosemore2019-11-261-0/+6
| | | | | | | | | | | | | | In GCC 10, the default at -O2 is now -ftree-loop-distribute-patterns. This optimization causes GCC to "helpfully" convert the hand-written loop in _dl_start into a call to memset, which is not available that early in program startup. Similar problems in other places in GLIBC have been addressed by explicitly building with -fno-tree-loop-distribute-patterns, but this one may have been overlooked previously because it only affects targets where HAVE_BUILTIN_MEMSET is not defined. This patch fixes a bug observed on nios2-linux-gnu target that caused all programs to segv on startup.
* Introduce DL_LOOKUP_FOR_RELOCATE flag for _dl_lookup_symbol_xFlorian Weimer2019-11-211-1/+2
| | | | | | | | | | This will allow changes in dependency processing during non-lazy binding, for more precise processing of NODELETE objects: During initial relocation in dlopen, the fate of NODELETE objects is still unclear, so objects which are depended upon by NODELETE objects cannot immediately be marked as NODELETE.

* Enhance _dl_catch_exception to allow disabling exception handlingFlorian Weimer2019-11-161-0/+12
| | | | | | | | | | | | In some cases, it is necessary to introduce noexcept regions where raised dynamic loader exceptions (e.g., from lazy binding) are fatal, despite being nested in a code region with an active exception handler. This change enhances _dl_catch_exception with to provide such a capability. The existing function is reused, so that it is not necessary to introduce yet another function with a similar purpose.

* Introduce link_map_audit_state accessor functionFlorian Weimer2019-11-158-43/+70
| | | | | | | | | | | | To improve GCC 10 compatibility, it is necessary to remove the l_audit zero-length array from the end of struct link_map. In preparation of that, this commit introduces an accessor function for the audit state, so that it is possible to change the representation of the audit state without adjusting the code that accesses it.

* Rename and split elf/tst-dlopen-aout collection of testsFlorian Weimer2019-10-178-24/+177
| | | | | | | | | | | | | | | From the beginning, elf/tst-dlopen-aout has exercised two different bugs: (a) failure to report errors for a dlopen of the executable itself in some cases (bug 24900) and (b) incorrect rollback of the TLS modid allocation in case of a dlopen failure (bug 16634). This commit replaces the test with elf/tst-dlopen-self for (a) and elf/tst-dlopen-tlsmodid for (b). The latter tests use the elf/tst-dlopen-self binaries (or iconv) with dlopen, so they are no longer self-dlopen tests. Tested on x86_64-linux-gnu and i686-linux-gnu, with a toolchain that does not default to PIE.

* elf: Assign TLS modid later during dlopen [BZ #24930]Florian Weimer2019-10-043-30/+48
| | | | | | | | | | | | | | Commit a42faf59d6d9f82e5293a9ebcc26d9c9e562b12b ("Fix BZ #16634.") attempted to fix a TLS modid consistency issue by adding additional checks to the open_verify function. However, this is fragile because open_verify cannot reliably predict whether _dl_map_object_from_fd will later fail in the more complex cases (such as memory allocation failures). Therefore, this commit assigns the TLS modid as late as possible. At that point, the link map pointer will eventually be passed to _dl_close, which will undo the TLS modid assignment.

* MIPS support for GNU hashMihailo Stojanovic2019-08-293-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a reimplementation of [1], which was submitted back in 2015. Copyright issue has been sorted [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (GT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering of the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word at the beggining of the section, which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue reported in [3] which is caused by the leading word of the .MIPS.xhash section. Leading word is now removed in the corresponding binutils patch, and the number of entries in the translation table is computed using DT_MIPS_SYMTABNO dynamic tag. Since the MIPS specific dl-lookup.c file was removed following the initial patch submission, I opted for the definition of three new macros in the generic ldsodefs.h. ELF_MACHINE_GNU_HASH_ADDRIDX defines the index of the dynamic tag in the l_info array. ELF_MACHINE_HASH_SYMIDX is used to calculate the index of a symbol in GNU hash. On MIPS, it is defined to look up the symbol index in the translation table. ELF_MACHINE_XHASH_SETUP is defined for MIPS only. It initializes the .MIPS.xhash pointer in the link_map_machine struct. The other major change is bumping the highest EI_ABIVERSION value for MIPS to suggest that the dynamic linker now supports GNU hash. The patch was tested by running the glibc testsuite for the three MIPS ABIs (o32, n32 and n64) and for x86_64-linux-gnu.

* elf: Self-dlopen failure with explict loader invocation [BZ #24900]Florian Weimer2019-08-154-25/+94
| | | | | | | | | | | | | | | | | | | | In case of an explicit loader invocation, ld.so essentially performs a dlopen call to load the main executable. Since the pathname of the executable is known at this point, it gets stored in the link map. In regular mode, the pathname is not known and "" is used instead. As a result, if a program calls dlopen on the pathname of the main program, the dlopen call succeeds and returns a handle for the main map. This results in an unnecessary difference between glibc testing (without --enable-hardcoded-path-in-tests) and production usage. This commit discards the names when building the link map in _dl_new_object for the main executable, but it still determines the origin at this point in case of an explict loader invocation. The reason is that the specified pathname has to be used; the kernel has a different notion of the main executable.
* elf: Support elf/tst-dlopen-aout in more configurationsFlorian Weimer2019-08-122-13/+14
| | | | | | | | | | | | dlopen can no longer open PIE binaries, so it is not necessary to link the executable as non-PIE to trigger a dlopen failure. If we hard-code the path to the real executable, we can run the test with and without hard-coded paths because the dlopen path will not be recognized as the main program in both cases. (With an explict loader invocation, the loader currently adds argv[0] to l_libname for the main map and the dlopen call suceeds as a result; it does not do that in standard mode.)

| | | | | | | | | | | | | | | | | | | This change should be fully backwards-compatible because the old code aborted the load if a soname mismatch was encountered (instead of searching further for a matching symbol). This means that no different symbols are found. The soname check was explicitly disabled for the skip_map != NULL case. However, this only happens with dl(v)sym and RTLD_NEXT, and those lookups do not come with a verneed entry that could be used for the check. The error check was already explicitly disabled for the skip_map != NULL case, that is, when dl(v)sym was called with RTLD_NEXT. But _dl_vsym always sets filename in the struct r_found_version argument to NULL, so the check was not active anyway. This means that symbol lookup results for the skip_map != NULL case do not change, either.

| | | | | | | | | | | | | | | | | | | | | | | | The elf/tst-pldd (added by 1a4c27355e146 to fix BZ#18035) test does not expect the hardcoded paths that are output by pldd when the test is built with --enable-hardcoded-path-in-tests. Instead of showing the ABI installed library names for loader and libc (such as ld-linux-x86-64.so.2 and libc.so.6 for x86_64), pldd shows the default built ld.so and libc.so. It makes the tests fail with an invalid expected loader/libc name. This patch fixes the elf-pldd test by adding the canonical ld.so and libc.so names in the expected list of possible outputs when parsing the result output from pldd. The test now handles both default build and --enable-hardcoded-path-in-tests option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 9182aa67994 (Fix vDSO l_name for GDB's, BZ#387) the initial link_map for executable itself and loader will have both l_name and l_libname->name holding the same value due: elf/dl-object.c 95 new->l_name = *realname ? realname : (char *) newname->name + libname_len - 1; Since newname->name points to new->l_libname->name. This leads to pldd to an infinite call at: elf/pldd-xx.c 203 again: 204 while (1) 205 { 206 ssize_t n = pread64 (memfd, tmpbuf.data, tmpbuf.length, name_offset); 228 /* Try the l_libname element. */ 229 struct E(libname_list) ln; 230 if (pread64 (memfd, &ln, sizeof (ln), m.l_libname) == sizeof (ln)) 231 { 232 name_offset = ln.name; 233 goto again; 234 } Since the value at ln.name (l_libname->name) will be the same as previously read.

For Linux, kernel already provides supports through the syscall and Hurd HTL lacks __pthread_clock_gettime and __pthread_clock_settime internal implementation. As described in clock_gettime man-page [1] on 'Historical note for SMP system', implementing CLOCK_{THREAD,PROCESS}_CPUTIME_ID with timer registers is error-prone and susceptible to timing and accurary issues that the libc can not deal without kernel support. This allows removes unused code which, however, still incur in some runtime overhead in thread creation (the struct pthread cpuclock_offset initialization).
