ipcpd: Wait for DHT running state before access

2017-12-06T16:05:13+00:00

The DHT will now wait for the DHT_RUNNING state before handling request messages, ensuring that the parameters are set correctly before they are read and sent at JOIN. Also fixes a re-introduced assertion failure when a JOIN fails. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix missing bracket in DHT

2017-12-05T20:38:18+00:00

ca2f47d had a missing bracket after a last-minute update to simplify the logic. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Update DHT buckets in JOINING state

2017-12-05T20:27:38+00:00

The DHT buckets were not updated in JOINING state, which sometimes caused the DHT to miss its first peer update when joining and become isolated. This also checks if a name is already registered to avoid adding it multiple times. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Only update DHT buckets in running state

2017-11-28T20:38:02+00:00

This fixes accessing buckets when a DHT join fails. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Create new SDUs for DHT join retries

2017-11-07T10:25:21+00:00

The DHT join operation left an SDU in the rdrbuff for a couple of seconds during retries, which may cause the system to block if there is heavy traffic. This patch releases the sdb when the write fails and creates a new packet for every retry. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Deprecate ouroboros_init and ourboros_fini

2017-10-14T11:19:10+00:00

This commit deprecates ouroboros_init and ouroboros_fini and adds them as a constructor or destructor, causing these function to be run automatically when a program that links to the library calls and exits main(). For this to fully work, the library had to be split so that we can avoid the irmd calling these functions (the IRMd has to create the shm structures on which these calls depend). The library is split in 3 parts: libouroboros-dev, libouroboros-irm and libouroboros-common. The latter is linked to the other two so that including libouroboros-dev or libouroboros-irm will also link libouroboros-common.

lib: Cancel tpm threads instead of marking exit

2017-09-30T15:58:18+00:00

This makes the threadpool use pthread_cancel instead of setting an exit flag that threadpool managed threads check periodically. This drastically reduces CPU consumption in the irmd when running a lot of applications. It requires cancellation handlers in the ipcp and irmd to be implemented to ensure safe cancellation during operation and shutdown.

ipcpd: normal: Set clock to realtime clock

2017-09-26T09:02:03+00:00

A pthread_cond_wait was using the pthread_cond_clock and thereby timing out constantly, consuming 100% CPU. This changes it to use the realtime clock.

ipcpd: Fix deadlock in DHT

2017-09-24T20:00:20+00:00

The lookup_update was waiting for the LU_INIT state to resolve under dht->lock which prevented that update. This PR fixes this bug, but leaves a (very rare) bug when the lookup_destroy is called while the lookup_update is waiting for the LU_INIT state to resolve. The solution also is a (harmless) lock inversion, but this is also not the best. Fixes #51 Fixes #52
