ovsdb: Explicitly ignore sscanf() return value in is_valid_version().

The return value isn't interesting here: it will always be 0.

Coverity #10698.

test-ovsdb: Check uuid_from_string() return value.

dhcp-client: Remove useless call to timeout() from send_reliably().

timeout() has no side effects so calling it without looking at the return
value is pointless.

Coverity #10700.

commit 1611cf3f5abbff87b4443d2807b369fdd327eb49
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=1611cf3f5abbff87b4443d2807b369fdd327eb49

ovs-vsctl: Clarify that uuid_from_string() shouldn't fail in post_create().

Coverity #10701.

commit fbca1e20e84bc34537f0a3db073195f6783fb373
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=fbca1e20e84bc34537f0a3db073195f6783fb373

ovs-kill: Remove.

This utility isn't used anywhere (except INSTALL.Linux), so remove it.

Coverity #10708.

commit 4a433a0fc58cd29612d349bf0fc4da73d97d0aed
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=4a433a0fc58cd29612d349bf0fc4da73d97d0aed

ovs-vsctl: Simplify parse_column_key_value().

Coverity pointed out some inconsistencies on tests for whether columnp and
keyp were nonnull.  These tests were, at best, confusing, but in fact every
caller always passed nonnull for both parameters, so this commit drops all
of those tests.

Coverity #10715, 10710.

commit 1cec7ca1a2d9341b6c69d9b6c19792b341db3f6e
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=1cec7ca1a2d9341b6c69d9b6c19792b341db3f6e

ovs-brcompatd: Simplify code in brc_recv_update().

This code was baffling and it confused Coverity, too.

Coverity #11070.

commit 0f0b102dcf5c067259788e54a0a5352851ed1565
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=0f0b102dcf5c067259788e54a0a5352851ed1565

ovsdb-idl: JSONRPC_REPLY message always has nonnull 'id'.

A JSONRPC_REPLY message always have a nonnull 'id' member, as ensured by
jsonrpc_msg_is_valid().  Checking for NULL here confused Coverity into
believing that the call to ovsdb_idl_txn_process_reply() just below could
cause a null pointer dereference, since ovsdb_idl_txn_process_reply() uses
the 'id' member without checking it for null.

Coverity #10713.

commit 82c2b79de650665f18d847c1771d28430486225e
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=82c2b79de650665f18d847c1771d28430486225e

rconn: Clarify rconn_run_wait().

At first glance the vconn_wait() call looks risky because this function
checked whether rc->vconn is nonnull at the top.  In fact it's OK because
rc->state will be S_ACTIVE or S_IDLE only if rc->vconn is nonnull, but
there's no harm in putting that check inside the block that only runs if
rc->vconn is nonnull.

Coverity #10714.

commit 93e039fb5e7ae77a556e1d144ca069a86555598b
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=93e039fb5e7ae77a556e1d144ca069a86555598b

leak-checker: Avoid printing freed pointer.

I think that this will work OK, and it should avoid complaints from static
checkers about using a freed pointer.

Coverity #11069.

commit c55acc2eed76ae17667fa5f65f5f3c347b796926
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=c55acc2eed76ae17667fa5f65f5f3c347b796926

stream: Make stream_report_content() tolerate negative size.

A negative size probably means that a system call failed.  The caller could
set that to 0 but we might as well just tolerate it in
stream_report_content() by making the parameter type signed.

Coverity #10718.

commit fe81a2987abeda195f6535cab973b1c753cca4b3
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=fe81a2987abeda195f6535cab973b1c753cca4b3
Author: Ben Pfaff <blp at nicira.com>

process: Avoid late failure if /dev/null cannot be opened.

It is (very slightly) risky to open /dev/null every time that we need it,
because open can fail.  So this commit opens /dev/null in advance instead.

Coverity #10719.
