2018-11-26Implementation of preadv2 for Linux 4.4 supportZach Koopmans
Implement RWF_HIPRI (4.6) silently passes the read call. Implement -1 offset calls readv. PiperOrigin-RevId: 222840324 Change-Id: If9ddc1e8d086e1a632bdf5e00bae08205f95b6b0
2018-11-08Implement sync_file_range()Andrei Vagin
sync_file_range - sync a file segment with disk In Linux, sync_file_range() accepts three flags: SYNC_FILE_RANGE_WAIT_BEFORE Wait upon write-out of all pages in the specified range that have already been submitted to the device driver for write-out before performing any write. SYNC_FILE_RANGE_WRITE Initiate write-out of all dirty pages in the specified range which are not presently submitted write-out. Note that even this may block if you attempt to write more than request queue size. SYNC_FILE_RANGE_WAIT_AFTER Wait upon write-out of all pages in the range after performing any write. In this implementation: SYNC_FILE_RANGE_WAIT_BEFORE without SYNC_FILE_RANGE_WAIT_AFTER isn't supported right now. SYNC_FILE_RANGE_WRITE is skipped. It should initiate write-out of all dirty pages, but it doesn't wait, so it should be safe to do nothing while nobody uses SYNC_FILE_RANGE_WAIT_BEFORE. SYNC_FILE_RANGE_WAIT_AFTER is equal to fdatasync(). In Linux, sync_file_range() doesn't writes out the file's meta-data, but fdatasync() does if a file size is changed.

2018-11-08Create stubs for syscalls upto Linux 4.4.Rahat Mahmood
Create syscall stubs for missing syscalls upto Linux 4.4 and advertise a kernel version of 4.4. PiperOrigin-RevId: 220667680 Change-Id: Idbdccde538faabf16debc22f492dd053a8af0ba7
2018-10-20Add more unimplemented syscall eventsFabricio Voznika
Added events for *ctl syscalls that may have multiple different commands. For runsc, each syscall event is only logged once. For *ctl syscalls, use the cmd as identifier, not only the syscall number. PiperOrigin-RevId: 218015941 Change-Id: Ie3c19131ae36124861e9b492a7dbe1765d9e5e59

2018-08-10Implemented the splice(2) syscall.Justine Olshan
Currently the implementation matches the behavior of moving data between two file descriptors. However, it does not implement this through zero-copy movement. Thus, this code is a starting point to build the more complex implementation. PiperOrigin-RevId: 208284483 Change-Id: Ibde79520a3d50bc26aead7ad4f128d2be31db14e
2018-08-02Add seccomp(2) support.Brian Geffon
Add support for the seccomp syscall and the flag SECCOMP_FILTER_FLAG_TSYNC. PiperOrigin-RevId: 207101507 Change-Id: I5eb8ba9d5ef71b0e683930a6429182726dc23175
