* Add TCP_TX_DELAY from Linux 5.3 to netinet/tcp.h.Joseph Myers2019-09-272-0/+5
| | | | | | | | | This patch adds the new TCP_TX_DELAY constant from Linux 5.3 to sysdeps/gnu/netinet/tcp.h. Tested for x86_64. * sysdeps/gnu/netinet/tcp.h (TCP_TX_DELAY): New macro.
* y2038: Introduce struct __timespec64 - new internal glibc typeLukasz Majewski2019-09-262-0/+28
| | | | | | | | | | | | | This type is a glibc's "internal" type similar to struct timespec but whose tv_sec field is a __time64_t rather than a time_t, which makes it Y2038-proof and usable to pass syscalls between user code and Y2038-proof kernel. To support passing this structure to the kernel - the unnamed 32 bit padding bit-field has been introduced. The placement of it depends on the endianness of the SoC. Tested on x86_64 and ARM.

* inet/net-internal.h: Fix uninitalised clntudp_call() variableAlistair Francis2019-09-242-0/+17
| | | | | | | | | | | | | | | | | The total_deadline variable inside the clntudp_call() function inside sunrpc/clnt_udp.c can cause uninitalised variable warnings when building with GCC 8.3 or 9.2 on a platform with a 64-bit tv_nsec on a 32-bit architecture. To fix the warning let's use the DIAG_* macros to hide the warning.

* Script to generate ChangeLog-like output from git logSiddhesh Poyarekar2019-09-205-0/+1244
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Co-authored-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br> Reviewed-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br> Reviewed-by: Joseph Myers <joseph@codesourcery.com> The utility of a ChangeLog file has been discussed in various mailing list threads and GNU Tools Cauldrons in the past years and the general consensus is that while the file may have been very useful in the past when revision control did not exist or was not as powerful as it is today, it's current utility is fast diminishing. Further, the ChangeLog format gets in the way of modernisation of processes since it almost always results in rewriting of a commit, thus preventing use of any code review tools to automatically manage patches in the glibc project. There is consensus in the glibc community that documentation of why a change was done (i.e. a detailed description in a git commit) is more useful than what changed (i.e. a ChangeLog entry) since the latter can be deduced from the patch. The GNU community would however like to keep the option of ascertaining what changed through a ChangeLog-like output and as a compromise, it was proposed that a script be developed that generates this output. The script below is the result of these discussions. This script takes two git revisions references as input and generates the git log between those revisions in a form that resembles a ChangeLog. Its capabilities and limitations are listed in a comment in the script. On a high level it is capable of parsing C code and telling what changed at the top level, but not within constructs such as functions. Design ------ At a high level, the script analyses the raw output of a VCS, parses the source files that have changed and attempts to determine what changed. The script driver needs three distinct components to be fully functional for a repository: - A vcstocl_quirks.py file that helps it parse weird patterns in sources that may result from preprocessor defines. - A VCS plugin backend; the git backend is implemented for glibc - A programming language parser plugin. C is currently implemented. Additional programming language parsers can be added to give more detailed output for changes in those types of files. For input in languages other than those that have a parser, the script only identifies if a file has been added, removed, modified, permissions changed, etc. but cannot understand the change in content. The C Parser ------------ The C parser is capable of parsing C programs with preprocessor macros in place, as if they were part of the language. This presents some challenges with parsing code that expands macros on the fly and to help work around that, a vcstocl_quirks.py file has transformations to ease things. The C parser currently can identify macro definitions and scopes and all global and static declarations and definitions. It cannot parse (and compare) changes inside functions yet, it could be a future enhancement if the need for it arises. Testing ------- The script has been tested with the glibc repository up to glibc-2.29 and also in the past with emacs. While it would be ideal to have something like this in a repository like gnulib, that should not be a bottleneck for glibc to start using this, so this patch proposes to add these scripts into glibc. And here is (hopefully!) one of the last ChangeLog entries we'd have to write for glibc: * scripts/gitlog_to_changelog.py: New script to auto-generate ChangeLog. * scripts/vcs_to_changelog/frontend_c.py: New file. * scripts/vcs_to_changelog/misc_util.py: New file. * scripts/vcs_to_changelog/vcs_git.py: New file. * scripts/vcs_to_changelog/vcstocl_quirks.py: Likewise.
* [powerpc] SET_RESTORE_ROUND optimizations and bug fixPaul A. Clarke2019-09-193-25/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SET_RESTORE_ROUND brackets a block of code, temporarily setting and restoring the rounding mode and letting everything else, including exceptions generated within the block, pass through. On powerpc, the current code clears the exception enables, which will hide exceptions generated within the block. This issue was introduced by me in commit e905212627350d54b58426214b5a54ddc852b0c9. Fix this by not clearing exception enable bits in the prologue. Also, since we are no longer changing the enable bits in either the prologue or the epilogue, there is no need to test for entering/exiting non-stop mode. Also, optimize the prologue get/save/set rounding mode operations for POWER9 and later by using 'mffscrn' when possible. Suggested-by: Paul E. Murphy <murphyp@linux.ibm.com> Reviewed-by: Paul E.

* Fix RISC-V vfork build with Linux 5.3 kernel headers.Joseph Myers2019-09-182-1/+11
| | | | | | | | | | | | | | | | | | | | | Building glibc for RISC-V with Linux 5.3 kernel headers fails because <linux/sched.h>, included in vfork.S for CLONE_* constants, contains a structure definition not safe for inclusion in assembly code. All other architectures already avoid use of that header in vfork.S, either defining the CLONE_* constants locally or embedding the required values directly in the relevant instruction, where they implement vfork using the clone syscall (see the implementations for aarch64, ia64, mips and nios2). This patch makes the RISC-V version define the constants locally like the other architectures. Tested build for all three RISC-V configurations in build-many-glibcs.py with Linux 5.3 headers. * sysdeps/unix/sysv/linux/riscv/vfork.S: Do not include <linux/sched.h>. (CLONE_VM): New macro.

* alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]Aurelien Jarno2019-09-144-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On alpha, Linux kernel 5.1 added the standard getegid, geteuid and getppid syscalls (commit ecf7e0a4ad15287). Up to now alpha was using the corresponding OSF1 syscalls through: - sysdeps/unix/alpha/getegid.S - sysdeps/unix/alpha/geteuid.S - sysdeps/unix/alpha/getppid.S When building against kernel headers >= 5.1, the glibc now use the new syscalls through sysdeps/unix/sysv/linux/syscalls.list. When it is then used with an older kernel, the corresponding 3 functions fail. A quick fix is to move the OSF1 wrappers under the sysdeps/unix/sysv/linux/alpha directory so they override the standard linux ones. A better fix would be to try the new syscalls and fallback to the old OSF1 in case the new ones fail. This can be implemented in a later commit.

* Use __attribute_pure__ macro in bits/mathcalls.hGabriel F. T. Gomes2019-09-051-2/+2
| | | | | | | | | When the const attribute of totalorder* functions was replaced with the pure attribute, by commit ID ab41100bab12, it did not use the __attribute_pure__ macro, but the __attribute__ ((__pure__)) statement.

Debugging showed that the test case is passing arguments incorrectly to totalorderl. This can also be inferred by the fact that compiling the test case with -O0 hides the bug. The documentation for the const attribute in GCC manual reads: Note that a function that has pointer arguments and examines the data pointed to must not be declared const if the pointed-to data might change between successive invocations of the function. In general, since a function cannot distinguish data that might change from data that cannot, const functions should never take pointer or, in C++, reference arguments. Likewise, a function that calls a non-const function usually must not be const itself. Since the pointed-to data is likely to be changed by user code between invocations of totalorder*, this patch removes the const attribute from the declarations of all totalorder functions, replacing it with the pure attribute, as suggested in the manual: The pure attribute imposes similar but looser restrictions on a function’s definition than the const attribute: pure allows the function to read any non-volatile memory, even if it changes in between successive invocations of the function. Tested for powerpc64le and x86_64.

* Finish move of clock_* functions to libc. [BZ #24959]Zack Weinberg2019-09-0472-243/+382
| | | | | | | | | | | | | | | | In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/.

* Add misc/tst-mntent-autofs, testing autofs "ignore" filteringFlorian Weimer2019-09-023-1/+148

* Use autofs "ignore" mount hint in getmntent_r/getmntentIan Kent2019-09-022-12/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically autofs mounts were not included in mount table listings. This is the case in other SysV autofs implementations and was also the case with Linux autofs. But now that /etc/mtab is a symlink to the proc filesystem mount table the autofs mount entries appear in the mount table on Linux. Prior to the symlinking of /etc/mtab mount table it was sufficient to call mount(2) and simply not update /etc/mtab to exclude autofs mounts from mount listings. Also, with the symlinking of /etc/mtab we have seen a shift in usage toward using the proc mount tables directly. But the autofs mount entries need to be retained when coming from the proc file system for applications that need them (largely autofs file system users themselves) so filtering out these entries within the kernel itself can't be done. So it needs be done in user space. There are three reasons to omit the autofs mount entries. One is that certain types of auto-mounts have an autofs mount for every entry in their autofs mount map and these maps can be quite large. This leads to mount table listings containing a lot of unnecessary entries. Also, this change in behaviour between autofs implementations can cause problems for applications that use getmntent(3) in other OS implementations as well as Linux. Lastly, there's very little that user space can do with autofs mount entries since this must be left to the autofs mount owner, typically the automount daemon. But it can also lead to attempts to access automount managed paths resulting mounts being triggered when they aren't needed or mounts staying mounted for much longer thay they need be. While the point of this change ins't to help with these problems (and it can be quite a problem) it may be a welcome side effect. So the Linux autofs file system has been modified to accept a pseudo mount option of "ignore" (as is used in other OS implementations) so that user space can use this as a hint to skip autofs entries on reading the mount table. The Linux autofs automount daemon used getmntent(3) itself and has been modified to use the proc file system directly so that it can "ignore" mount option. The use of this mount option is opt-in and a configuration option has been added which defaults to not use this option so if there are applications that need these entries, other than autofs itself, they can be retained. Also, since this filtering is based on an added mount option earlier versions of Linux autofs iand other autofs file system users will not use the option and so won't be affected by the change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following: - On error, poll must not return without polling, including EBADF, and instead report POLLHUP/POLLERR/POLLNVAL - Select must report EBADF if some set contains an invalid FD. The idea is to move error management to after all select calls, in the poll/select final treatment. The error is instead recorded in a new `error' field, and a new SELECT_ERROR bit set. Thanks Svante Signell for the initial version of the patch. * hurd/hurdselect.c (SELECT_ERROR): New macro.

Return EBADF there is any bit set above _hurd_dtablesize. - Do not request io_select on bogus descriptors (SELECT_ERROR). - On io_select request error, record the error. - On io_select bogus reply, use EIO error code. - On io_select bogus or error reply, record the error. - Do not destroy reply port for bogus FDs. - On error, make poll set POLLHUP in the EPIPE case, POLLNVAL in the EBADF case, or else POLLERR. - On error, make select simulated readiness.
* hurd: Fix timeout handling in _hurd_selectRichard Braun2019-08-303-41/+87
| | | | | | | | | | | | | | | | | | | Rely on servers to implement timeouts, so that very short values (including 0) don't make mach_msg return before valid replies can be received.

| | | | | | | | | | | | The function attempts to optimize this case by performing one IPC system call with the timeout included among the parameters, but in the absence of a reply, it will call mach_msg again with the same timeout later, effectively doubling the total timeout of the select/poll call.

* MIPS support for GNU hashMihailo Stojanovic2019-08-299-8/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
