Joseph Myers	9da45337e4	Fix deprecated utcnow() usage in build-many-glibcs.py Running build-many-glibcs.py with Python 3.12 or later produces a warning: build-many-glibcs.py:566: DeprecationWarning: datetime.datetime.utcnow() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.now(datetime.UTC). build_time = datetime.datetime.utcnow() Replace with datetime.datetime.now(datetime.timezone.utc) (the datetime.UTC constant is new in 3.11, so not suitable for use in this script at present).	2 years ago

Adhemerval Zanella	460860f457	Remove ia64-linux-gnu Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

H.J. Lu	0f9afc265a	x32: Handle displacement overflow in PLT rewrite [BZ #31218 ] PLT rewrite calculated displacement with ElfW(Addr) disp = value - branch_start - JMP32_INSN_SIZE; On x32, displacement from 0xf7fbe060 to 0x401030 was calculated as unsigned int disp = 0x401030 - 0xf7fbe060 - 5; with disp == 0x8442fcb and caused displacement overflow. The PLT entry was changed to: 0xf7fbe060 <+0>: e9 cb 2f 44 08 jmp 0x401030 0xf7fbe065 <+5>: cc int3 0xf7fbe066 <+6>: cc int3 0xf7fbe067 <+7>: cc int3 0xf7fbe068 <+8>: cc int3 0xf7fbe069 <+9>: cc int3 0xf7fbe06a <+10>: cc int3 0xf7fbe06b <+11>: cc int3 0xf7fbe06c <+12>: cc int3 0xf7fbe06d <+13>: cc int3 0xf7fbe06e <+14>: cc int3 0xf7fbe06f <+15>: cc int3 x32 has 32-bit address range, but it doesn't wrap address around at 4GB, JMP target was changed to 0x100401030 (0xf7fbe060LL + 0x8442fcbLL + 5), which is above 4GB.

Define ELF_DYNAMIC_AFTER_RELOC for x86-64 to rewrite the PLT section with direct branch after relocation when the lazy binding is disabled. PLT rewrite is disabled by default since SELinux may disallow modifying code pages and ld.so can't detect it in all cases.

H.J. Lu	35694d3416	x86-64/cet: Check the restore token in longjmp setcontext and swapcontext put a restore token on the old shadow stack which is used to restore the target shadow stack when switching user contexts. When longjmp from a user context, the target shadow stack can be different from the current shadow stack and INCSSP can't be used to restore the shadow stack pointer to the target shadow stack. Update longjmp to search for a restore token. If found, use the token to restore the shadow stack pointer before using INCSSP to pop the shadow stack. Stop the token search and use INCSSP if the shadow stack entry value is the same as the current shadow stack pointer. It is a user error if there is a shadow stack switch without leaving a restore token on the old shadow stack. The only difference between __longjmp.S and __longjmp_chk.S is that __longjmp_chk.S has a check for invalid longjmp usages. Merge __longjmp.S and __longjmp_chk.S by adding the CHECK_INVALID_LONGJMP macro. Reviewed-by: Noah Goldstein <goldstein.w.n@gmail.com>	2 years ago
