* Properly handle --disable-default-pie [BZ #28780]H.J. Lu2022-01-172-32/+55
| | | | | | | | | | | | When --disable-default-pie is used, all glibc programs and the testsuite should be built as position dependent executables (non-PIE), regardless if the build compiler supports PIE or static PIE. When --disable-default-pie is used, don't build static PIE by default. This fixes BZ #28780. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* elf: Fix 64 time_t support for installed statically binariesAdhemerval Zanella2022-01-176-39/+39
| | | | | | | | | | | | | | The usage of internal static symbol for statically linked binaries does not work correctly for objects built with -D_TIME_BITS=64, since the internal definition does not provide the expected aliases. This patch makes it to use the default stat functions instead (which uses the default 64 time_t alias and types). Checked on i686-linux-gnu.

* elf: Set l_contiguous to 1 for the main map in more casesFlorian Weimer2022-01-171-0/+25
| | | | | | | | | | | | | | | | | l_contiguous was not initialized at all for the main map and always 0. This commit adds code to check if the LOAD segments are adjacent to each other, and sets l_contiguous accordingly. This helps _dl_find_object because it is more efficient if the main mapping is contiguous. Note that not all (PIE or non-PIE) binaries are contiguous in this way because BFD ld creates executables with LOAD holes: ELF LOAD segments creating holes in the process image on GNU/Linux https://sourceware.org/pipermail/binutils/2022-January/119082.html https://sourceware.org/bugzilla/show_bug.cgi?id=28743 Reviewed-by: H.J.

* i386: Remove broken CAN_USE_REGISTER_ASM_EBP (bug 28771)Florian Weimer2022-01-134-255/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The configure check for CAN_USE_REGISTER_ASM_EBP tried to compile a simple function that uses %ebp as an inline assembly operand. If compilation failed, CAN_USE_REGISTER_ASM_EBP was set 0, which eventually had these consequences: (1) %ebx was avoided as an inline assembly operand, with an assembler macro hack to avoid unnecessary register moves. (2) %ebp was avoided as an inline assembly operand, using an out-of-line syscall function for 6-argument system calls. (1) is no longer needed for any GCC version that is supported for building glibc. %ebx can be used directly as a register operand. Therefore, this commit removes the %ebx avoidance completely. This avoids the assembler macro hack, which turns out to be incompatible with the current Systemtap probe macros (which switch to .altmacro unconditionally). (2) is still needed in many build configurations. The existing configure check cannot really capture that because the simple function succeeds to compile, while the full glibc build still fails. Therefore, this commit removes the check, the CAN_USE_REGISTER_ASM_EBP macro, and uses the out-of-line syscall function for 6-argument system calls unconditionally. Reviewed-by: H.J.

* debug: Synchronize feature guards in fortified functions [BZ #28746]Siddhesh Poyarekar2022-01-126-15/+58
| | | | | | | | | | | | | | | | | | 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.
