tpm: infineon section mismatch

2008-02-06T18:41:10+00:00

Fix section mismatch by making the driver template variable name match one of the whitelisted variable names in modpost. WARNING: vmlinux.o(.data+0x7a9e8): Section mismatch: reference to .init.text:tpm_inf_pnp_probe (between 'tpm_inf_pnp' and 'cn_idx') Signed-off-by: Randy Dunlap Cc: Marcel Selhorst Acked-by: Sam Ravnborg Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

tpm.c: fix crash during device removal

2008-02-06T18:41:04+00:00

The clean up procedure now uses platform device "release" callback to handle memory clean up. For this purpose "release" function callback was added to struct tpm_vendor_specific, so hw device driver provider can get called when it is safe to remove all allocated resources. This is supposed to fix a bug in device removal, where device while in receive function (waiting on timeout) was prone to segfault, if the tpm_chip struct was unallocated before the timeout expired (in tpm_remove_hardware).

TPM: fix suspend and resume failure

2008-01-14T16:52:22+00:00

The savestate command structure was being overwritten by the result of running the TPM_SaveState command after one run, so make it a local variable to the function instead of a global variable that gets overwritten.

TPM: fix TIS device driver locality request

2007-11-29T17:24:52+00:00

During the initialization of the TPM TIS driver, the necessary locality has to be requested earlier in the init-process. Depending on the used TPM chip, this leads to wrong information. For example: Lenovo X61s with Atmel TPM: tpm_tis 00:0a: 1.2 TPM (device-id 0xFFFF, rev-id 255) But correct is: tpm_tis 00:0c: 1.2 TPM (device-id 0x3203, rev-id 9) This short patch fixes this issue.

tpm: pay attention to IRQ info from PNP

2007-10-17T15:42:51+00:00

If we discover the TIS TPM device via PNP, use the PNP IRQ information rather than probing for an IRQ. If PNP shows no IRQ, run the TPM in polling mode. Tested-by: Signed-off-by: Bjorn Helgaas Cc: Kylene Hall Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

tpmdd maintainers

2007-08-23T02:52:44+00:00

Fix up the maintainers info in the tpm drivers. Kylene will be out for some time, so copying the sourceforge list is the best way to get some attention. Cc: Marcel Selhorst Cc: Kylene Jo Hall Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fix memory leak in tpm_binary_bios_measurements_open()

2007-07-20T19:00:04+00:00

The same problem that was fixed for tpm_ascii_bios_measurements_open() in commit 178554ae75739e91dc4d7c3e42a3db95448cc5bf also occurs in tpm_binary_bios measurements(). Thanks for noticing this Satyam! I tested the attached patch to fix tpm_binary_bios_measurments as well. Signed-off-by: Reiner Sailer Signed-off-by: Linus Torvalds

Memory leak in tpm_ascii_bios_measurements_open()

2007-07-20T15:44:20+00:00

Coverity found a memory leak in tpm_ascii_bios_measurements_open(). If "read_log(log)" fails, then we may leak 'log' and 'log->bios_event_log'. Signed-off-by: Jesper Juhl Cc: Seiji Munetoh Cc: Stefan Berger Cc: Reiner Sailer Cc: Kylene Hall Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
