[libvirt] [PATCH 1/2] virStrndup: Accept negative values as string length

It may shorten the code a bit as the following pattern: VIR_STRNDUP(dst, src, cond ? n : strlen(src)) is used on several places among our code.

[libvirt] [PATCH] cgroups: Do not enforce nonexistent controllers
by Viktor Mihajlovski 24 May '13

24 May '13

Currently, the controllers argument to virCgroupDetect acts both as a result filter and a required controller specification, which is a bit overloaded. If both functionalities are needed, it would be better to have them seperated into a filter and a requirement mask. The only situation where it is used today is to ensure that only CPU related controllers are used for the VCPU directories. But here we clearly do not want to enforce the existence of cpu, cpuacct and specifically not cpuset at the same time. This commit changes the semantics of controllers to "filter only". Should a required mask ever be needed, more work will have to be done.

Within whole vircgroup.c we 'return -errno', e.g. 'return -ENOMEM'. However, in this specific function virCgroupAddTaskStrController we weren't returning -ENOMEM but -1 despite fact that later in the function we are returning one of errno values indeed. --- Notes: Pushing under trivial rule. This change has been sort of ACKed previously though: https://www.redhat.com/archives/libvir-list/2013-May/msg01731.html However, Eric suggested to be pushed as a separate patch. src/util/vircgroup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/util/vircgroup.c b/src/util/vircgroup.c index cc144a5..13b7332 100644 --- a/src/util/vircgroup.c +++ b/src/util/vircgroup.c @@ -1028,7 +1028,7 @@ static int virCgroupAddTaskStrController(virCgroupPtr group, char *endp; if (!(str = strdup(pidstr))) - return -1; + return -ENOMEM; cur = str; while (*cur != '\0') { -- 1.8.2.1
