2023-07-05Exclude routines from fortificationFrédéric Bérat1-6/+6
Since the _FORTIFY_SOURCE feature uses some routines of Glibc, they need to be excluded from the fortification. On top of that: - some tests explicitly verify that some level of fortification works appropriately, we therefore shouldn't modify the level set for them. - some objects need to be build with optimization disabled, which prevents _FORTIFY_SOURCE to be used for them. Assembler files that implement architecture specific versions of the fortified routines were not excluded from _FORTIFY_SOURCE as there is no C header included that would impact their behavior.

These functions are about to be added to POSIX, under Austin Group issue 986.

2022-11-08Linux: Add ppoll fortify symbol for 64 bit time_t (BZ# 29746)Adhemerval Zanella1-12/+29
Similar to ppoll, the poll.h header needs to redirect the poll call to a proper fortified ppoll with 64 bit time_t support. The implementation is straightforward, just need to add a similar check as __poll_chk and call the 64 bit time_t ppoll version. The debug fortify tests are also extended to cover 64 bit time_t for affected ABIs. Unfortunately it requires an aditional symbol, which makes backport tricky. One possibility is to add a static inline version if compiler supports is and call abort instead of __chk_fail, so fortified version will call __poll64 in the end. Another possibility is to just remove the fortify support for _TIME_BITS=64. Checked on i686-linux-gnu.
2022-09-05debug: test for more required cacellation points (BZ# 29274)Adhemerval Zanella1-3/+3
Generalize the test for cancellation point in __read_chk to also test the other fortified functions with required cancellation points. Since there is not easy way to force some syscalls to block (for instance pread) the test tests two modes: cancellation on blocked syscalls and early cancellation on pending request. Checked on x86_64-linux-gnu and aarch64-linux-gnu. Co-authored-by: Andreas Schwab <schwab@suse.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2022-06-22debug: make __read_chk a cancellation point (bug 29274)Andreas Schwab1-0/+7
The __read_chk function, as the implementation behind the fortified read function, must be a cancellation point, thus it cannot use INLINE_SYSCALL.
2022-01-12debug: Synchronize feature guards in fortified functions [BZ #28746]Siddhesh Poyarekar1-2/+8
Some functions (e.g. stpcpy, pread64, etc.) had moved to POSIX in the main headers as they got incorporated into the standard, but their fortified variants remained under __USE_GNU. As a result, these functions did not get fortified when _GNU_SOURCE was not defined. Add test wrappers that check all functions tested in tst-chk0 at all levels with _GNU_SOURCE undefined and then use the failures to (1) exclude checks for _GNU_SOURCE functions in these tests and (2) Fix feature macro guards in the fortified function headers so that they're the same as the ones in the main headers.

2022-01-06debug: Remove catchsegv and libSegfault (BZ #14913)Adhemerval Zanella1-17/+2
Trapping SIGSEGV within the process is error-prone, adds security issues, and modern analysis design tends to happen out of the process (either by attaching a debugger or by post-mortem analysis). The libSegfault also has some design problems, it uses non async-signal-safe function (backtrace) on signal handler. There are multiple alternatives if users do want to use similar functionality, such as sigsegv gnulib module or libsegfault.

/bin/bash instead (FYI, this is a repost of https://sourceware.org/pipermail/libc-alpha/2019-July/105035.html now that FSF papers have been signed and confirmed on FSF side). This trivial patch attemps to fix BZ 24106. Basically the bash locally used when building glibc on the host shall not leak on the installed glibc, as the system where it is installed might be different and use another bash location. So I have looked for all occurences of @BASH@ or $(BASH) in installed files, and replaced it by /bin/bash. This was suggested by Florian Weimer in the bug report.

2018-12-05Use PRINTF_FORTIFY instead of _IO_FLAGS2_FORTIFY (bug 11319)Zack Weinberg1-1/+1
The _chk variants of all of the printf functions become much simpler. This is the last thing that we needed _IO_acquire_lock_clear_flags2 for, so it can go as well. I took the opportunity to make the headers included and the names of all local variables consistent across all the affected files. Since we ultimately want to get rid of __no_long_double as well, it must be possible to get all of the nontrivial effects of the _chk functions by calling the _internal functions with appropriate flags. For most of the __(v)xprintf_chk functions, this is covered by PRINTF_FORTIFY plus some up-front argument checks that can be duplicated. However, __(v)sprintf_chk installs a custom jump table so that it can crash instead of overflowing the output buffer. This functionality is moved to __vsprintf_internal, which now has a 'maxlen' argument like __vsnprintf_internal; to get the unsafe behavior of ordinary (v)sprintf, pass -1 for that argument. obstack_printf_chk and obstack_vprintf_chk are no longer in the same file. As a side-effect of the unification of both fortified and non-fortified vdprintf initialization, this patch fixes bug 11319 for __dprintf_chk and __vdprintf_chk, which was previously fixed only for dprintf and vdprintf by the commit commit 7ca890b88e6ab7624afb1742a9fffb37ad5b3fc3 Author: Ulrich Drepper <drepper@redhat.com> Date: Wed Feb 24 16:07:57 2010 -0800 Fix reporting of I/O errors in *dprintf functions. This patch adds a test case to avoid regressions. Tested for powerpc and powerpc64le.
