Title
mtd: spi-nor: sst: Fix SST write failure
Summary
In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: sst: Fix SST write failure 'commit 18bcb4aa54ea ("mtd: spi-nor: sst: Factor out common write operation to `sst_nor_write_data()`")' introduced a bug where only one byte of data is written, regardless of the number of bytes passed to sst_nor_write_data(), causing a kernel crash during the write operation. Ensure the correct number of bytes are written as passed to sst_nor_write_data(). Call trace: [ 57.400180] ------------[ cut here ]------------ [ 57.404842] While writing 2 byte written 1 bytes [ 57.409493] WARNING: CPU: 0 PID: 737 at drivers/mtd/spi-nor/sst.c:187 sst_nor_write_data+0x6c/0x74 [ 57.418464] Modules linked in: [ 57.421517] CPU: 0 UID: 0 PID: 737 Comm: mtd_debug Not tainted 6.12.0-g5ad04afd91f9 #30 [ 57.429517] Hardware name: Xilinx Versal A2197 Processor board revA - x-prc-02 revA (DT) [ 57.437600] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 57.444557] pc : sst_nor_write_data+0x6c/0x74 [ 57.448911] lr : sst_nor_write_data+0x6c/0x74 [ 57.453264] sp : ffff80008232bb40 [ 57.456570] x29: ffff80008232bb40 x28: 0000000000010000 x27: 0000000000000001 [ 57.463708] x26: 000000000000ffff x25: 0000000000000000 x24: 0000000000000000 [ 57.470843] x23: 0000000000010000 x22: ffff80008232bbf0 x21: ffff000816230000 [ 57.477978] x20: ffff0008056c0080 x19: 0000000000000002 x18: 0000000000000006 [ 57.485112] x17: 0000000000000000 x16: 0000000000000000 x15: ffff80008232b580 [ 57.492246] x14: 0000000000000000 x13: ffff8000816d1530 x12: 00000000000004a4 [ 57.499380] x11: 000000000000018c x10: ffff8000816fd530 x9 : ffff8000816d1530 [ 57.506515] x8 : 00000000fffff7ff x7 : ffff8000816fd530 x6 : 0000000000000001 [ 57.513649] x5 : 0000000000000000 x4 : 0000000000000000 x3 : 0000000000000000 [ 57.520782] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff0008049b0000 [ 57.527916] Call trace: [ 57.530354] sst_nor_write_data+0x6c/0x74 [ 57.534361] sst_nor_write+0xb4/0x18c [ 57.538019] mtd_write_oob_std+0x7c/0x88 [ 57.541941] mtd_write_oob+0x70/0xbc [ 57.545511] mtd_write+0x68/0xa8 [ 57.548733] mtdchar_write+0x10c/0x290 [ 57.552477] vfs_write+0xb4/0x3a8 [ 57.555791] ksys_write+0x74/0x10c [ 57.559189] __arm64_sys_write+0x1c/0x28 [ 57.563109] invoke_syscall+0x54/0x11c [ 57.566856] el0_svc_common.constprop.0+0xc0/0xe0 [ 57.571557] do_el0_svc+0x1c/0x28 [ 57.574868] el0_svc+0x30/0xcc [ 57.577921] el0t_64_sync_handler+0x120/0x12c [ 57.582276] el0t_64_sync+0x190/0x194 [ 57.585933] ---[ end trace 0000000000000000 ]--- [pratyush@kernel.org: add Cc stable tag]
