From: Michael Holzheu There is a race between lcs_stopcard() and lcs_open_device() which can lead to the error 'lcs: Error in starting channel, rc=-16'. lcs_open_device() is invoked when 'ifconfig up' is called due to a hotplug event, which is caused by register_netdev(). In parallel lcs_stopcard() is executed. Both functions are sending lcs commands. The second invocation fails with -EBUSY (-16) as return value. Move invocation of register_netdev() after invocation of lcs_stopcard to avoid the race.

From: Frank Pavlic qeth network driver related changes: - due to OSA hardware changes in TCP Segmentation Offload support we are able now to pack TSO packets too. This fits perfectly in design of qeth buffer handling and sending data respectively. - remove skb_realloc_headroom from the sending path since hard_header_len value provides enough headroom now. - device recovery behaviour improvement - bug fixed in Enhanced Device Driver Packing functionality Signed-off-by: Frank Pavlic --- drivers/s390/net/Makefile | 2 +- drivers/s390/net/qeth.h | 41 ++++--- drivers/s390/net/qeth_eddp.c | 40 +++---- drivers/s390/net/qeth_main.c | 145 +++++++++++++++++------- drivers/s390/net/qeth_tso.c | 256 ------------------------------------------- drivers/s390/net/qeth_tso.h | 193 ++++++++++++++++++++------------ 6 files changed, 273 insertions(+), 404 deletions(-) delete mode 100644 drivers/s390/net/qeth_tso.c (limited to 'drivers/s390') diff --git a/drivers/s390/net/Makefile b/drivers/s390/net/Makefile index 85b590c5701d..90d4d0ef3dd4 100644 --- a/drivers/s390/net/Makefile +++ b/drivers/s390/net/Makefile @@ -10,6 +10,6 @@ obj-$(CONFIG_SMSGIUCV) += smsgiucv.o obj-$(CONFIG_CTC) += ctc.o fsm.o cu3088.o obj-$(CONFIG_LCS) += lcs.o cu3088.o obj-$(CONFIG_CLAW) += claw.o cu3088.o -qeth-y := qeth_main.o qeth_mpc.o qeth_sys.o qeth_eddp.o qeth_tso.o +qeth-y := qeth_main.o qeth_mpc.o qeth_sys.o qeth_eddp.o qeth-$(CONFIG_PROC_FS) += qeth_proc.o obj-$(CONFIG_QETH) += qeth.o diff --git a/drivers/s390/net/qeth.h b/drivers/s390/net/qeth.h index d13c105f74e6..a755b57db46b 100644 --- a/drivers/s390/net/qeth.h +++ b/drivers/s390/net/qeth.h @@ -24,7 +24,7 @@ #include "qeth_mpc.h" -#define VERSION_QETH_H "$Revision: 1.137 $" +#define VERSION_QETH_H "$Revision: 1.139 $" #ifdef CONFIG_QETH_IPV6 #define QETH_VERSION_IPV6 ":IPv6" @@ -370,6 +370,25 @@ struct qeth_hdr { } hdr;

During adapter shutdown it occurred that a request was cleaned up twice. First during its normal completion. Second when dismiss_all was called. The fix is to serialize access to fsf request list between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check and delete a fsf request from the list if its completion is triggered. (Additionally a rwlock was replaced by a spinlock and fsf_req_cleanup was eliminated.)
