2018-08-31Do not use fs.FileOwnerFromContext in fs/proc.file.UnstableAttr().Jamie Liu
From //pkg/sentry/context/context.go: // - It is *not safe* to retain a Context passed to a function beyond the scope // of that function call. Passing a stored kernel.Task as a context.Context to fs.FileOwnerFromContext violates this requirement. PiperOrigin-RevId: 211143021 Change-Id: I4c5b02bd941407be4c9cfdbcbdfe5a26acaec037

2018-08-14Fix `ls -laR | wc -l` hanging.Kevin Krakauer
stat()-ing /proc/PID/fd/FD incremented but didn't decrement the refcount for FD. This behavior wasn't usually noticeable, but in the above case: - ls would never decrement the refcount of the write end of the pipe to 0. - This caused the write end of the pipe never to close. - wc would then hang read()-ing from the pipe.

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.

2018-07-17Merge FileMem.usage in IncRefMichael Pratt
Per the doc, usage must be kept maximally merged. Beyond that, it is simply a good idea to keep fragmentation in usage to a minimum. The glibc malloc allocator allocates one page at a time, potentially causing lots of fragmentation. However, those pages are likely to have the same number of references, often making it possible to merge ranges. PiperOrigin-RevId: 204960339 Change-Id: I03a050cf771c29a4f05b36eaf75b1a09c9465e14
