* locale: Sort Makefile variables.Carlos O'Donell2024-01-101-29/+97
| | | | | | Sort Makefile variables using scrips/sort-makefile-lines.py. No regressions on x86_64.
* i386: Remove CET support bitsH.J. Lu2024-01-1012-89/+45
| | | | | | | | | | | | 1. Remove _dl_runtime_resolve_shstk and _dl_runtime_profile_shstk. 2. Move CET offsets from x86 cpu-features-offsets.sym to x86-64 features-offsets.sym. 3. Rename x86 cet-control.h to x86-64 feature-control.h since it is only for x86-64 and also used for PLT rewrite. 4. Add x86-64 ldsodefs.h to include feature-control.h. 5. Change TUNABLE_CALLBACK (set_plt_rewrite) to x86-64 only. 6. Move x86 dl-procruntime.c to x86-64. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* Fix deprecated utcnow() usage in build-many-glibcs.pyJoseph Myers2024-01-101-1/+1
| | | | | | | | | | | | 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).
* Fix invalid escape sequence in build-many-glibcs.pyJoseph Myers2024-01-101-1/+1
| | | | | | | | | | | | Running build-many-glibcs.py with Python 3.12 or later produces a warning: build-many-glibcs.py:173: SyntaxWarning: invalid escape sequence '\.' m = re.fullmatch('([0-9]+)\.([0-9]+)[.0-9]*', l) Use a raw string instead to avoid that warning. (Note: I haven't checked whether any other Python scripts included with glibc might have issues with newer Python versions.)

* Remove ia64-linux-gnuAdhemerval Zanella2024-01-08567-155609/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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].

* x32: Handle displacement overflow in PLT rewrite [BZ #31218]H.J. Lu2024-01-064-2/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add ELF_DYNAMIC_AFTER_RELOC to allow target specific processing after relocation. For x86-64, add #define DT_X86_64_PLT (DT_LOPROC + 0) #define DT_X86_64_PLTSZ (DT_LOPROC + 1) #define DT_X86_64_PLTENT (DT_LOPROC + 3) 1. DT_X86_64_PLT: The address of the procedure linkage table. 2. DT_X86_64_PLTSZ: The total size, in bytes, of the procedure linkage table. 3. DT_X86_64_PLTENT: The size, in bytes, of a procedure linkage table entry. With the r_addend field of the R_X86_64_JUMP_SLOT relocation set to the memory offset of the indirect branch instruction. 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. Use $ export GLIBC_TUNABLES=glibc.cpu.plt_rewrite=1 to enable PLT rewrite with 32-bit direct jump at run-time or $ export GLIBC_TUNABLES=glibc.cpu.plt_rewrite=2 to enable PLT rewrite with 32-bit direct jump and on APX processors with 64-bit absolute jump at run-time.

* hurd: Pass the data pointer to _hurd_stack_setup explicitlySergey Bugaev2024-01-043-9/+11
| | | | | | | | | Instead of relying on the stack frame layout to figure out where the stack pointer was prior to the _hurd_stack_setup () call, just pass the pointer as an argument explicitly. This is less brittle and much more portable. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-ID: <20240103171502.1358371-8-bugaevc@gmail.com>
* x86-64/cet: Check the restore token in longjmpH.J. Lu2024-01-043-145/+84
| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | Since shadow stack is only supported for x86-64, ignore --enable-cet for i386. Always setting $(enable-cet) for i386 to "no" to support ifneq ($(enable-cet),no) in x86 Makefiles. We can't use ifeq ($(enable-cet),yes) since $(enable-cet) can be "yes", "no" or "permissive".
