Subject: [PATCH] build: support explicitly disabling netcf
|
||||
|
||||
placing "-Dnetcf=disabled" on the meson commandline was ignored,
|
||||
meaning that even with that option the build would get WITH_NETCF if
|
||||
the netcf-devel package was found - the only way to disable it was to
|
||||
uninstall netcf-devel.
|
||||
|
||||
This patch adds the small bit of logic to check the netcf meson
|
||||
commandline option (in addition to whether netcf-devel is installed)
|
||||
before defining WITH_NETCF.

Subject: [PATCH] virSetUIDGIDWithCaps: Don't drop CAP_SETPCAP right away
|
||||
|
||||
There are few cases where we execute a virCommand with all caps
|
||||
cleared (virCommandClearCaps()). For instance
|
||||
dnsmasqCapsRefreshInternal() does just that. This means, that
|
||||
after fork() and before exec() the virSetUIDGIDWithCaps() is
|
||||
called. But since the caller did not want to change anything,
|
||||
just drop capabilities, these are the values of arguments:
|
||||
|
||||
virSetUIDGIDWithCaps (uid=-1, gid=-1, groups=0x0, ngroups=0,
|
||||
capBits=0, clearExistingCaps=true)
|
||||
|
||||
This means that indeed all capabilities will be dropped,
|
||||
including CAP_SETPCAP. But this capability controls whether
|
||||
capabilities can be set, IOW whether capng_apply() succeeds.
|
||||
|
||||
There are two calls of capng_apply() in the function. The
|
||||
CAP_SETPCAP is dropped after the first call and thus the other
|
||||
call (capng_apply(CAPNG_SELECT_BOUNDS);) fails.
|
||||
|
||||
The solution is to keep the capability for as long as needed
|
||||
(just like CAP_SETGID and CAP_SETUID) and drop it only at the
|
||||
very end (just like CAP_SETGID and CAP_SETUID).

Subject: [PATCH] virSetUIDGIDWithCaps: Set bounding capabilities only with
|
||||
CAP_SETPCAP
|
||||
|
||||
In one of my previous patches I've tried to postpone dropping
|
||||
CAP_SETPCAP until the very end because it's needed for
|
||||
capng_apply(). What I did not realize back then was that we might
|
||||
not have the capability to begin with. Because of unknown reasons
|
||||
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
|
||||
for CAPNG_SELECT_CAPS.
|
||||
|
||||
Reproducer is really simple: run libvirtd as a regular user.
|
||||
During its initialization, libvirtd will spawn some binaries
|
||||
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
|
||||
capabilities.
|
||||
|
||||
Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
|
||||
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

Subject: [PATCH 1/2] wireshark: Switch to tvb_bytes_to_str()
|
||||
|
||||
When the dissector sees a byte sequence that is either an opaque
|
||||
data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
|
||||
bytes as a hex numbers using our own implementation. But
|
||||
wireshark already provides a function for it: tvb_bytes_to_str().
|
||||
NB, the reason why it returns a const string is so that callers
|
||||
don't try to free it - the string is allocated using an allocator
|
||||
which will decide when to free it.
|
||||
|
||||
The wireshark formatter was introduced in wireshark commit of
|
||||
v1.99.2~479 and thus is present in the version we require at
|
||||
least (2.6.0).

Subject: [PATCH 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()
|
||||
|
||||
In the dissect_xdr_bytes() there's a comment that the string
|
||||
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
|
||||
that is expected because xdr_bytes() used plain calloc() AND the
|
||||
string is not an XDR struct but plain 'char *' type. Passing it
|
||||
to xdr_free() must result in weird things happening.
