2019-11-20Pass OpenTruncate to gofer in Open call when opening file with O_TRUNC.Nicolas Lacasse
Note that the Sentry still calls Truncate() on the file before calling Open. A new p9 version check was added to ensure that the p9 server can handle the the OpenTruncate flag. If not, then the flag is stripped before sending. PiperOrigin-RevId: 281609112

2019-06-18gvisor/fs: don't update file.offset for sockets, pipes, etcAndrei Vagin
sockets, pipes and other non-seekable file descriptors don't use file.offset, so we don't need to update it. With this change, we will be able to call file operations without locking the file.mu mutex. This is already used for pipes in the splice system call. PiperOrigin-RevId: 253746644

2018-07-31proc: show file flags in fdinfoAndrei Vagin
Currently, there is an attempt to print FD flags, but they are not decoded into a number, so we see something like this: /criu # cat /proc/self/fdinfo/0 flags: {%!o(bool=000false)} Actually, fdinfo has to contain file flags.

2018-06-21Implement ioctl(FIOASYNC)Ian Gudger
FIOASYNC and friends are used to send signals when a file is ready for IO. This may or may not be needed by Nginx. While Nginx does use it, it is unclear if the code that uses it has any effect. PiperOrigin-RevId: 201550828 Change-Id: I7ba05a7db4eb2dfffde11e9bd9a35b65b98d7f50
