2024-06-20linux-user: Make TARGET_NR_setgroups affect only the current threadIlya Leoshkevich
Like TARGET_NR_setuid, TARGET_NR_setgroups should affect only the calling thread, and not the entire process. Therefore, implement it using a syscall, and not a libc call.

2024-04-28linux-user: do_setsockopt: fix SOL_ALG.ALG_SET_KEYMichael Tokarev
This setsockopt accepts zero-lengh optlen (current qemu implementation does not allow this). Also, there's no need to make a copy of the key, it is enough to use lock_user() (which accepts zero length already).

2024-04-14linux-user/x86_64: Handle the vsyscall page in open_self_maps_{2,4}Richard Henderson
This is the only case in which we expect to have no host memory backing for a guest memory page, because in general linux user processes cannot map any pages in the top half of the 64-bit address space.

2024-03-05linux-user: Remove pgb_dynamic alignment assertionRichard Henderson
The assertion was never correct, because the alignment is a composite of the image alignment and SHMLBA. Even if the image alignment didn't match the image address, an assertion would not be correct -- more appropriate would be an error message about an ill formed image. But the image cannot be held to SHMLBA under any circumstances.

2023-11-02linux-user: Report AArch64 hwcap2 fields above bit 31Peter Maydell
The AArch64 ELF hwcap2 field is 64 bits, but our get_elf_hwcap2() works with uint32_t, so it accidentally fails to report any hwcaps over bit 31. Use uint64_t here. The Arm hwcap2 is only 32 bits (because the ELF format makes these fields be the size of "long" in the ABI), but since it shares the prototype declaration for get_elf_hwcap2() it is easier to also expand it to 64 bits. The only hwcap fields we implement already that are affected by this are the HBC and MOPS ones, neither of which were implemented in a previous release, so this doesn't need backporting to older stable branches.
