rds: check for excessive looping in rds_send_xmit

2019-08-15T19:04:24+00:00

Original commit from 2011 updated to include a change by Yuval Shaia that adds a new statistic counter "send_stuck_rm" to capture the messages looping exessively in the send path. Signed-off-by: Gerd Rausch Acked-by: Santosh Shilimkar Signed-off-by: David S. Miller

net/rds: Add a few missing rds_stat_names entries

2019-08-15T19:04:24+00:00

In a previous commit, fields were added to "struct rds_statistics" but array "rds_stat_names" was not updated accordingly. Please note the inconsistent naming of the string representations that is done in the name of compatibility with the Oracle internal code-base. s_recv_bytes_added_to_socket -> "recv_bytes_added_to_sock" s_recv_bytes_removed_from_socket -> "recv_bytes_freed_fromsock" Fixes: 192a798f5299 ("RDS: add stat for socket recv memory usage") Signed-off-by: Gerd Rausch Acked-by: Santosh Shilimkar Signed-off-by: David S.

net/rds: zero last byte for strncpy

2013-03-08T05:35:44+00:00

for NUL terminated string, need be always sure '\0' in the end. additional info: strncpy will pads with zeroes to the end of the given buffer. should initialise every bit of memory that is going to be copied to userland Signed-off-by: Chen Gang Signed-off-by: Ben Hutchings Signed-off-by: David S.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

RDS: remove init and exit annotation

2010-09-09T01:16:39+00:00

The trivial amount of memory saved isn't worth the cost of dealing with section mismatches. Signed-off-by: Zach Brown

RDS: Change send lock from a mutex to a spinlock

2010-09-09T01:12:12+00:00

This change allows us to call rds_send_xmit() from a tasklet, which is crucial to our new operating model. * Change c_send_lock to a spinlock * Update stats fields "sem_" to "_lock" * Remove unneeded rds_conn_is_sending() About locking between shutdown and send -- send checks if the connection is up. Shutdown puts the connection into DISCONNECTING. After this, all threads entering send will exit immediately. However, a thread could be *in* send_xmit(), so shutdown acquires the c_send_lock to ensure everyone is out before proceeding with connection shutdown. Signed-off-by: Andy Grover

RDS: Implement atomic operations

2010-09-09T01:11:41+00:00

Implement a CMSG-based interface to do FADD and CSWP ops. Alter send routines to handle atomic ops. Add atomic counters to stats. Add xmit_atomic() to struct rds_transport Inline rds_ib_send_unmap_rdma into unmap_rm Signed-off-by: Andy Grover

RDS: Export symbols from core RDS

2009-08-24T02:13:07+00:00

Now that rdma and tcp transports will be modularized, we need to export a number of functions so they can call them. Signed-off-by: Andy Grover Signed-off-by: David S. Miller

net: mark read-only arrays as const

2009-08-05T17:42:58+00:00

String literals are constant, and usually, we can also tag the array of pointers const too, moving it to the .rodata section. Signed-off-by: Jan Engelhardt Signed-off-by: David S. Miller
