efi_loader: fix build error for freestanding.o

2019-03-14T20:03:14+00:00

Since commit f51a226436a87 ("efi_loader: provide freestanding library") in
parallel builds errors

    lib/efi_selftest/../efi_loader/efi_freestanding.o:
    file not recognized: File truncated

occur. Obviously make cannot correctly sequence parallel builds with a
dependency like ../efi_loader/efi_freestanding.o.

efi_loader: Fix serial console size detection

2019-03-10T18:56:59+00:00

Function term_read_reply tries to read from the serial console until
the end_char was read. This can hang forever if we are, for some reason,
not able to read the full response (e.g. serial buffer too small,
frame error). This patch moves the timeout detection into
term_read_reply() to assure we will make progress.

Fixes: 6bb591f704 ("efi_loader: query serial console size reliably")
Signed-off-by: Matthias Brugger 

Throw missing error when an incomplete reply for the cursor position is
received.

Change type of argument of term_get_char() *s32. This renders the function
reusable in efi_cin_read_key().

efi_loader: HII protocols: debug messages

2019-03-02T22:34:26+00:00

When package types are not supported by our implementation of the HII
database protocol supported error messages are displayed.

Essentially the output is only needed for debugging. By using EFI_PRINT()
the messages are only written for in debug mode and with correct
indentation.

efi_loader: HII protocols: fix new_package_list()

2019-03-02T22:34:26+00:00

In new_package_list() we call new_packagelist() to create a new package
list. Next we try to add the packages which fails for form packages. Due
to this error we call free_packagelist(). Now in free_packagelist()
list_del() is called for an uninitialized field hii->link. This leads to
changing random memory addresses.

To solve the problem move the initialization of hii->link to
new_packagelist().

efi_loader: do not add \ in efi_fs_from_name()

2019-03-02T22:34:26+00:00

In the `efidebug boot add` command we do not want an unsolicited leading
backslash added to the file name.

There is no good reason to mark a loaded file with a backslash as absolute.
Anyway when reading files the file name will be interpreted as relative to
root directory of the device.

So let's get rid of this backslash.

efi_loader: fix entry count in bootmgr

2019-02-25T11:39:48+00:00

Since commit 914df75b0c97 ("efi_loader: fix EFI entry counting")
entry_count is already set to 1 before efi_bootmgr_load() is called. So we
should not increment it when entering the function.

Without the patch an assert error occurs in efi_get_variable() if DEBUG is
defined.

efi_loader: error message if BootOrder not defined

2019-02-25T11:39:47+00:00

For booting via `bootefi bootmgr` it is necessary that the EFI variable
BootOrder is defined. Provide a diagnostic message if the variable is
missing.

tpm: simplify: tpm_set_global_lock()

2019-02-19T13:55:43+00:00

When in pack_byte_string() memcpy() is called for size 0 the source buffer
address has no relevance. So we can use NULL here.

efi_loader: do not miss last relocation block

2019-02-16T14:51:14+00:00

If the last block in the relocation table contains only a single
relocation, the current coding ignores it.

Fix the determination of the end of the relocation table.
