Subject: [PATCH 1/9] Do not report OOM incorrectly
|
||||||
|
|
||||||
|
In case there is no file in the set to rotate `calloc(0, ...)` is called
|
||||||
|
, which might return NULL.
|
||||||
|
|
||||||
|
Order the check for a zero number of files first, to void calling calloc
|
||||||
|
with a size of zero.

Subject: [PATCH 2/9] Unify asprintf usage
|
||||||
|
|
||||||
|
Unify the error checking of asprintf(3).
|
||||||
|
|
||||||
|
Also reset the target string pointer to NULL on error, if it is non-
|
||||||
|
local, since the content is undefined according to the specification.
|
||||||
|
|
||||||
|
Also fix potential NULL-pointer usage in sprintf(3):
|
||||||
|
|
||||||
|
logrotate.c:1595:
|
||||||
|
rotNames->dirName = malloc(strlen(ld) + strlen(log->oldDir) + 2);
|
||||||
|
sprintf(rotNames->dirName, "%s/%s", ld, log->oldDir);

Subject: [PATCH 3/9] Update custom asprintf implementation
|
||||||
|
|
||||||
|
Check for vsnprintf(3) failures.
|
||||||
|
|
||||||
|
Silence conversion warnings.
|
||||||
|
|
||||||
|
Do not call exit(2) on allocation failure, but return -1 like the
|
||||||
|
specification says. All callers check the return value, since they
|
||||||
|
need to handle standard asprintf(3) implementations.

||||||

Subject: [PATCH 6/9] Limit scope of variable
|
||||||
|
|
||||||
|
Limit the scope of a variable, by splitting it into several distinct
|
||||||
|
block scope variables.
|
||||||
|
|
||||||
|
This makes some asprintf(3) calls obsolete, and improves readability by
|
||||||
|
splitting the purpose of the variable.

olddir /var/log/foo
