2018-12-06Convert ValueSet to a mapMichael Pratt
Unlike FlagSet, order doesn't matter here, so it can simply be a map. PiperOrigin-RevId: 224377910 Change-Id: I15810c698a7f02d8614bf09b59583ab73cba0514
2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-10-10Add seccomp filter configuration to ptrace stubs.Adin Scannell
This is a defense-in-depth measure. If the sentry is compromised, this prevents system call injection to the stubs. There is some complexity with respect to ptrace and seccomp interactions, so this protection is not really available for kernel versions < 4.8; this is detected dynamically. Note that this also solves the vsyscall emulation issue by adding in appropriate trapping for those system calls. It does mean that a compromised sentry could theoretically inject these into the stub (ignoring the trap and resume, thereby allowing execution), but they are harmless.

We accidentally set the wrong maximum. I've also added PATH_MAX and NAME_MAX to the linux abi package. PiperOrigin-RevId: 216221311 Change-Id: I44805fcf21508831809692184a0eba4cee469633
