Fix conditionals on mtrace-based tests (bug 31892)

2024-07-01T15:20:30Z

The conditionals for several mtrace-based tests in catgets, elf, libio, malloc, misc, nptl, posix, and stdio-common were incorrect leading to test failures when bootstrapping glibc without perl. The correct conditional for mtrace-based tests requires three checks: first checking for run-built-tests, then build-shared, and lastly that PERL is not equal to "no" (missing perl).

syslog: Fix heap buffer overflow in __vsyslog_internal (CVE-2023-6246)

2024-01-30T14:53:37Z

__vsyslog_internal did not handle a case where printing a SYSLOG_HEADER containing a long program name failed to update the required buffer size, leading to the allocation and overflow of a too-small buffer on the heap. This commit fixes that. It also adds a new regression test that uses glibc.malloc.check. Reviewed-by: Adhemerval Zanella Reviewed-by: Carlos O'Donell Tested-by: Carlos O'Donell

misc/bits/syslog.h: Clearly separate declaration from definition

2023-07-05T14:59:48Z

This allows to include bits/syslog-decl.h in include/sys/syslog.h and therefore be able to create the libc_hidden_builtin_proto (__syslog_chk) prototype. Reviewed-by: Siddhesh Poyarekar

misc/bits/select2.h: Clearly separate declaration from definitions

2023-07-05T14:59:48Z

The __fdelt_chk declaration needs to be available so that libc_hidden_proto can be used while not redefining __FD_ELT. Thus, misc/bits/select-decl.h is created to hold the corresponding prototypes. Reviewed-by: Siddhesh Poyarekar

Exclude routines from fortification

2023-07-05T14:59:48Z

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.

Reflow Makefile. Sort using updated scripts/sort-makefile-lines.py. Code generation is changed as routines are linked in sorted order as expected. No regressions on x86_64 and i686. Reviewed-by: Siddhesh Poyarekar
