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')

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.

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.

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.

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'.

Use menuconfig objects II - TPM

2007-07-16T16:05:40+00:00

Change Kconfig objects from "menu, config" into "menuconfig" so
that the user can disable the whole feature without having to
enter the menu first.
