The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. 2022-03-08T22:19:51Z Szabolcs Nagy nsz@port70.net 2021-05-25T20:53:18Z urn:sha1:f7d3db5bfc4c3b2315dd8c3137f0f332e1c6896a new syscall to change the properties of a mount or a mount tree using file descriptors which the new mount api is based on, see linux commit 2a1867219c7b27f928e2545782b86daaf9ad50bd fs: add mount_setattr() 2022-03-08T22:19:36Z Szabolcs Nagy nsz@port70.net 2021-03-07T19:21:34Z urn:sha1:b21f3ded780cc8fd8e510c99aeaf4a453d8c8a22 see linux commit b0a0c2615f6f199a656ed8549d7dce625d77aa77 epoll: wire up syscall epoll_pwait2 linux commit 58169a52ebc9a733aeb5bea857bc5daa71a301bb epoll: add syscall epoll_pwait2 epoll_wait with struct timespec timeout instead of int. no time32 variant. 2021-09-23T23:11:46Z Rich Felker dalias@aerifal.cx 2021-09-23T23:11:46Z urn:sha1:7be59733d71ada3a32a98622507399253f1d5e48 When the soft-float ABI for PowerPC was added in commit 5a92dd95c77cee81755f1a441ae0b71e3ae2bcdb, with Freescale cpus using the alternative SPE FPU as the main use case, it was noted that we could probably support hard float on them, but that it would involve determining some difficult ABI constraints. This commit is the completion of that work. The Power-Arch-32 ABI supplement defines the ABI profiles, and indeed ATR-SPE is built on ATR-SOFT-FLOAT. But setjmp/longjmp compatibility are problematic for the same reason they're problematic on ARM, where optional float-related parts of the register file are "call-saved if present". This requires testing __hwcap, which is now done. In keeping with the existing powerpc-sf subarch definition, which did not have fenv, the fenv macros are not defined for SPE and the SPEFSCR control register is left (and assumed to start in) the default mode. 2021-07-07T01:12:02Z Rich Felker dalias@aerifal.cx 2021-07-07T01:12:02Z urn:sha1:0fbd7d6683d04dcaa636df53e7fce69ece746241 the kernel structure has padding of the shm_segsz member up to 64 bits, as well as 2 unused longs at the end. somehow that was overlooked when the powerpc port was added, and it has been broken ever since; applications compiled with the wrong definition do not correctly see the shm_segsz, shm_cpid, and shm_lpid members. fixing the definition just by adding the missing padding would break the ABI size of the structure as well as the position of the time64 shm_atime and shm_dtime members we added at the end. instead, just move one of the unused padding members from the original end (before time64) of the structure to the position of the missing padding. this preserves size and preserves correct behavior of any compiled code that was already working. programs affected by the wrong definition need to be recompiled with the correct one. 2021-02-15T14:15:54Z Szabolcs Nagy nsz@port70.net 2020-12-19T20:12:31Z urn:sha1:fd285f9dec226ca9e5377888ee24e3f8f5ada49f mainly added to linux to allow a central process management service in android to give MADV_COLD|PAGEOUT hints for other processes, see linux commit ecb8ac8b1f146915aa6b96449b66dd48984caacc mm/madvise: introduce process_madvise() syscall: an external memory hinting API 2020-11-29T05:54:14Z Szabolcs Nagy nsz@port70.net 2020-10-24T10:15:43Z urn:sha1:3ba370fe8d9f450d351d710066fa20afad8ce3df see linux commit 9b4feb630e8e9801603f3cab3a36369e3c1cf88d arch: wire-up close_range() linux commit 278a5fbaed89dacd04e9d052f4594ffd0e0585de open: add close_range() 2020-09-09T21:21:03Z Szabolcs Nagy nsz@port70.net 2020-07-28T21:17:13Z urn:sha1:9b7ed9702ce8925a5a947ad3bdbba126fe955aaf the linux faccessat syscall lacks a flag argument that is necessary to implement the posix api, see linux commit c8ffd8bcdd28296a198f237cc595148a8d4adfbe vfs: add faccessat2 syscall 2020-09-09T21:19:55Z Szabolcs Nagy nsz@port70.net 2020-03-31T18:32:51Z urn:sha1:d990090384c6a468bb86962baf8bae7b6fd1d2bf also added clone3 on sh and m68k, on sh it's still missing (not yet wired up), but reserved so safe to add. see linux commit fddb5d430ad9fa91b49b1d34d0202ffe2fa0e179 open: introduce openat2(2) syscall linux commit 9a2cef09c801de54feecd912303ace5c27237f12 arch: wire up pidfd_getfd syscall linux commit 8649c322f75c96e7ced2fec201e123b2b073bf09 pid: Implement pidfd_getfd syscall linux commit e8bb2a2a1d51511e6b3f7e08125d52ec73c11139 m68k: Wire up clone3() syscall 2020-08-27T22:36:45Z Rich Felker dalias@aerifal.cx 2020-08-25T02:45:51Z urn:sha1:57f6e85c9de417fef5eece2a5b00c1104321f543 dtv_copy, canary2, and canary_at_end existed solely to match multiple ABI and asm-accessed layouts simultaneously. now that pthread_arch.h can be included before struct __pthread is defined, the struct layout can depend on macros defined by pthread_arch.h.
