2006-12-02NetLabel: make netlbl_lsm_secattr struct easier/quicker to understandPaul Moore
The existing netlbl_lsm_secattr struct required the LSM to check all of the fields to determine if any security attributes were present resulting in a lot of work in the common case of no attributes. This patch adds a 'flags' field which is used to indicate which attributes are present in the structure; this should allow the LSM to do a quick comparison to determine if the structure holds any security attributes. Example: if (netlbl_lsm_secattr->flags) /* security attributes present */ else /* NO security attributes present */ Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
2006-12-02NetLabel: change netlbl_secattr_init() to return voidPaul Moore
The netlbl_secattr_init() function would always return 0 making it pointless to have a return value. This patch changes the function to return void. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
2006-12-02NetLabel: convert the unlabeled accept flag to use RCUPaul Moore
Currently the NetLabel unlabeled packet accept flag is an atomic type and it is checked for every non-NetLabel packet which comes into the system but rarely ever changed. This patch changes this flag to a normal integer and protects it with RCU locking. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
2006-12-02NetLabel: use gfp_t instead of int where it makes sensePaul Moore
There were a few places in the NetLabel code where the int type was being used instead of the gfp_t type, this patch corrects this mistake. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>

2006-12-02[DCCP] CCID2: Code optimizationsAndrea Bittau
These are code optimizations which are relevant when dealing with large windows. They are not coded the way I would like to, but they do the job for the short-term. This patch should be more neat. Commiter note: Changed the seqno comparisions to use {after,before}48 to handle wrapping.

2006-12-02[DCCP]: Introduce DCCP_{BUG{_ON},CRIT} macros, use enum:8 for the ccid3 statesGerrit Renker
This patch tackles the following problem: * the ccid3_hc_{t,r}x_sock define ccid3hc{t,r}x_state as `u8', but in reality there can only be a few, pre-defined enum names * this necessitates addiditional checking for unexpected values which would otherwise be caught by the compiler Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
