* Remove --with-default-link configure optionAdhemerval Zanella Netto2023-03-278-51/+7
| | | | | | | Now that there is no need to use a special linker script to hardening internal data structures, remove the --with-default-link configure option and associated definitions. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* libio: Remove the usage of __libc_IO_vtablesAdhemerval Zanella Netto2023-03-2722-513/+637
| | | | | | | | | | | | | | Instead of using a special ELF section along with a linker script directive to put the IO vtables within the RELRO section, the libio vtables are all moved to an array marked as data.relro (so linker will place in the RELRO segment without the need of extra directives). To avoid static linking namespace issues and including all vtable referenced objects, all required function pointers are set to weak alias. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | Instead define the required fields in system dependend files. The only system dependent definition is FILENAME_MAX, which should match POSIX PATH_MAX, and it is obtained from either kernel UAPI or mach headers. Currently set pre-defined value from current kernels. It avoids a circular dependendy when including stdio.h in gen-as-const-headers files.

* Move libc_freeres_ptrs and libc_subfreeres to hidden/weak functionsAdhemerval Zanella Netto2023-03-2790-243/+584
| | | | | | | | | | | | | | | | | | | | They are both used by __libc_freeres to free all library malloc allocated resources to help tooling like mtrace or valgrind with memory leak tracking. The current scheme uses assembly markers and linker script entries to consolidate the free routine function pointers in the RELRO segment and to be freed buffers in BSS. This patch changes it to use specific free functions for libc_freeres_ptrs buffers and call the function pointer array directly with call_function_static_weak. It allows the removal of both the internal macros and the linker script sections. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* stdio-common: tests: don't double-define _FORTIFY_SOURCESam James2023-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exactly the same as 35bcb08eaa953c9b8bef6ab2486dc4361e1f26c0. If using -D_FORITFY_SOURCE=3 (in my case, I've patched GCC to add =3 instead of =2 (we've done =2 for years in Gentoo)), building glibc tests will fail on tst-bz11319-fortify2 like: ``` <command-line>: error: "_FORTIFY_SOURCE" redefined [-Werror] <built-in>: note: this is the location of the previous definition cc1: all warnings being treated as errors ``` It's just because we're always setting -D_FORTIFY_SOURCE=2 rather than unsetting it first. If F_S is already 2, it's harmless, but if it's another value (say, 1, or 3), the compiler will bawk. (I'm not aware of a reason this couldn't be tested with =3, but the toolchain support is limited for that (too new), and we want to run the tests everywhere possible.) As Siddhesh noted previously, we could implement some fallback logic to determine the maximal F_S value supported by the toolchain, which is a bit easier now that autoconf-archive has been updated for F_S=3 (https://github.com/autoconf-archive/autoconf-archive/pull/269), but let's revisit this if it continues to crop up.

| | | | | | | | | | | | | | | | | Linux threads were removed about 12 years ago and the current nptl implementation only requires 4-byte alignment for pthread locks. The 16-byte alignment causes various issues.

| | | | | | | | | | | | | | | | WG14 recently accepted two additions to the printf/scanf %b/%B support: there are now PRIb* and SCNb* macros in <inttypes.h>, and printf %B is now an optional feature defined in normative text, instead of recommended practice, with corresponding PRIB* macros that can also be used to test whether that optional feature is supported. See N3072 items 14 and 15 for details (those changes were accepted, some other changes in that paper weren't). Add the corresponding PRI* macros to glibc and update one place in the manual referring to %B as recommended. (SCNb* should naturally be added at the same time as the corresponding scanf %b support.)

* C2x scanf binary constant handlingJoseph Myers2023-03-02127-29/+2582
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2x adds binary integer constants starting with 0b or 0B, and supports those constants for the %i scanf format (in addition to the %b format, which isn't yet implemented for scanf in glibc). Implement that scanf support for glibc. As with the strtol support, this is incompatible with previous C standard versions, in that such an input string starting with 0b or 0B was previously required to be parsed as 0 (with the rest of the input potentially matching subsequent parts of the scanf format string). Thus this patch adds 12 new __isoc23_* functions per long double format (12, 24 or 36 depending on how many long double formats the glibc configuration supports), with appropriate header redirection support (generally very closely following that for the __isoc99_* scanf functions - note that __GLIBC_USE (DEPRECATED_SCANF) takes precedence over __GLIBC_USE (C2X_STRTOL), so the case of GNU extensions to C89 continues to get old-style GNU %a and does not get this new feature). The function names would remain as __isoc23_* even if C2x ends up published in 2024 rather than 2023. When scanf %b support is added, I think it will be appropriate for all versions of scanf to follow C2x rules for inputs to the %b format (given that there are no compatibility concerns for a new format). Tested for x86_64 (full glibc testsuite). The first version was also tested for powerpc (32-bit) and powerpc64le (stdio-common/ and wcsmbs/ tests), and with build-many-glibcs.py.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "We don't need it any more" The INTR_MSG_TRAP macro in intr-msg.h used to play little trick with the stack pointer: it would temporarily save the "real" stack pointer into ecx, while setting esp to point to just before the message buffer, and then invoke the mach_msg trap. This way, INTR_MSG_TRAP reused the on-stack arguments laid out for the containing call of _hurd_intr_rpc_mach_msg (), passing them to the mach_msg trap directly. This, however, required special support in hurdsig.c and trampoline.c, since they now had to recognize when a thread is inside the piece of code where esp doesn't point to the real tip of the stack, and handle this situation specially. Commit 1d20f33ff4fb634310f27493b7b87d0b20f4a0b0 has removed the actual temporary change of esp by actually re-pushing mach_msg arguments onto the stack, and popping them back at end. It did not, however, deal with the rest of "the ecx kludge" code in other files, resulting in potential crashes if a signal arrives in the middle of pushing arguments onto the stack. Fix that by removing "the ecx kludge". Instead, when we want a thread to skip the RPC, but cannot make just make it jump to after the trap since it's not done adjusting the stack yet, set the SYSRETURN register to MACH_SEND_INTERRUPTED (as we do anyway), and rely on the thread itself for detecting this case and skipping the RPC. This simplifies things somewhat and paves the way for a future x86_64 port of this code. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-Id: <20230301162355.426887-1-bugaevc@gmail.com>
