Public bug reported:
[Impact]
Sysdig doesn't print filename when tracing a process - this, among other
things, breaks the qa kernel team ubuntu_sysdig_smoke test.
[How to reproduce]
$ sudo ~/bin/sysdig -p%evt.info proc.name=dd &
$ dd if=/dev/zero bs=1024 count=5 > /dev/null
This is actual output:
...
fd=0 size=1024
res=1024 data=
fd=1 size=1024
fd=0 size=1024
fd=1 size=1024
fd=0 size=1024
fd=1 size=1024
fd=0 size=1024
fd=1 size=1024
fd=0 size=1024
fd=1 size=1024
fd=0
...
while this is the expected/correct output:
...
fd=0(<f>/dev/zero) size=1024
res=1024
data=................................................................................
fd=1(<f>/dev/null) size=1024
res=1024
data=................................................................................
fd=0(<f>/dev/zero) size=1024
res=1024
data=................................................................................
fd=1(<f>/dev/null) size=1024
res=1024
data=................................................................................
fd=0(<f>/dev/zero) size=1024
res=1024
data=................................................................................
fd=1(<f>/dev/null) size=1024
res=1024
data=................................................................................
fd=0(<f>/dev/zero) size=1024
res=1024
data=................................................................................
fd=1(<f>/dev/null) size=1024
res=1024
data=................................................................................
fd=0(<f>/dev/zero) size=1024
res=1024
data=................................................................................
fd=1(<f>/dev/null) size=1024
res=1024
data=................................................................................
fd=0(<f>/dev/zero)
...
[Fix]
Cherry-pick an upstream commit that entered the 0.26.5 dev cycle:
https://github.com/draios/sysdig/commit/bbed8dab66157c0be0275040510ef189764582dd
[Regression potential]
Low, it's a clean upstream cherry pick.
