scsi: bfa: Fix function pointer type mismatch for state machines

2024-02-27T02:16:48Z

The bfa driver is full of state machines and a generic abstraction layer for them. This relies on casting function pointers, but that is no longer allowed when CONFIG_CFI_CLANG is enabled and causes a huge number of warnings like: drivers/scsi/bfa/bfad.c:169:3: error: cast from 'void (*)(struct bfad_s *, enum bfad_sm_event)' to 'bfa_sm_t' (aka 'void (*)(void *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] bfa_sm_set_state(bfad, bfad_sm_created); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Rework the mechanism to no longer require the function pointer casts, by having separate types for each individual state machine. This in turn requires moving the enum definitions for each state machine into the header files in order to define the typedef.

scsi: bfa: Remove additional unnecessary struct declarations

2024-02-27T02:16:33Z

Commit c3b0d087763f ("scsi: bfa: Remove unnecessary struct declarations") removed duplicate struct declarations for struct bfa_fcs_s and struct bfa_fcs_fabric_s. However, there are further duplications: - struct bfad_vf_s is declared in line 165 remove the duplication in line 834. - struct bfad_rport_s is declared in line 394 remove the duplication in line 836. Remove them. Signed-off-by: Simone Weiß Link: https://lore.kernel.org/r/20240217191409.6260-1-simone.p.weiss@posteo.com Signed-off-by: Martin K. Petersen

struct bfa_fcs_s is declared twice. First is declared at line 50, remove the duplicate. struct bfa_fcs_fabric_s is defined at line 175, remove unnecessary declaration.

scsi: bfa: remove bfa_fcs_mod_s

2017-01-10T04:34:58Z

Just call the functions directly instead of obsfucating the call chain. This was in reply to a patch from Kees Cook to constify the function pointer struct bfa_fcs_mod_s, but it turns out there is no reason to have this indirection at all.

bfa: fix bfa_fcb_itnim_alloc() error handling

2016-05-10T02:18:42Z

The caller assumes that "itnim" is NULL on error and non-NULL on success but really "itnim" is uninitialized on error. This function should just use normal error handling where it returns zero on success and negative on failure. Signed-off-by: Dan Carpenter Acked-by: Anil Gurumurthy Signed-off-by: Martin K. Petersen

This patch fixes a crash when tried setting symbolic name for an offline vport through sysfs. Crash is due to uninitialized pointer lport->ns, which gets initialized only on linkup (port online). Signed-off-by: Vijaya Mohan Guvva Cc: stable@vger.kernel.org Signed-off-by: James Bottomley

1. While FRU VPD data update, inform firmware to send a completion event on I2C bus. Without this change, firmware used to send completion message on I2C bus for every chunk of FRU VPD update. 2. Support for FRU VPN update on CHINOOK2 cards. 3. Append port count to the model name to differentiate between single port and dual port model of 1860. 4.
