sss_mc_set_recycled is a static function, that should not
be used outside nsssrv_mmap_cache.c. The sss_cache tool
is an exception, because in the case when sssd is not running,
sss_cache must invalidate the memory cache file. That is why
sss_mc_set_recycled was copied to the tools_mc_util.c
(as helper function for sss_memcache_invalidate function).
It was duplicated to allow this function to remain static
(and invisible to any .h files), so that it is not used anywhere else.
Wrong usage of this function might cause race conditions and corrupt
the cache.
I'll add comments about the duplication to the code.

This patch adds debug message for the case if sssd
fails to open old mc file for some other reason than
the file does not exist.
|

File descriptors leaked every time sss_mmap_cache_reinit was
called and also the old memory cache was still maped in memory
(munmap was not called). This patch adds destructor for memory
cache context to call close() and munmap() automaticly.

If a fatal EFAULT error is returned by the internal function that frees used
memory invalidate the whole cache and reinit it. This way we avoid further
corruption and insure clients see consistent data.
Also insure we use the right context in init() and we use talloc_zfree() in
reinit so that if the init() later fails we do not leave around a pointer
to free memory in the callers.
|
|
We should never try to invalidate an already invalid record as
internal pointers will not be consistent. Carefully test that the
record really is valid when we are fishing for free space, and
properly invalidate records or return a fatal error if something
goes wrong.
In order to make the code more robust always invalidate the whole
data space on initialization by setting all bits to 1, and make sure
to invalidate the whole last allocated slot by converting rec->len to
the number of slots instead of just the space used.
|
|
We were holding up slots when entries were invalidated directly an not through
our primitive garbage collection scheme.
|
|
Although it should enver happen that we pass in an invalid hash it
is always better to just not do anything than access memory ouf of
the hash table. It can lead to segfaults, or worse referencing
memory that should not be touched.
|
|
This is to allow to freely call mc functions even if initialization failed.
They will now gracefully fail instead of segfaulting.

The function is short enough so that we can simply stick with return and
release resources before returning as appropriate.
|
|
These functions can be called from the nss responder to invalidate
records that have ceased to exist or that need to be refreshed the
first time an application needs them.

Les copy/paste and chance of errors when setting basic record fields
that are shared among all object types.
