2022-04-05staging: rtl8712: fix a potential memory leak in r871xu_drv_init()Xiaoke Wang2-4/+3
In r871xu_drv_init(), if r8712_init_drv_sw() fails, then the memory allocated by r8712_alloc_io_queue() in r8712_usb_dvobj_init() is not properly released as there is no action will be performed by r8712_usb_dvobj_deinit(). To properly release it, we should call r8712_free_io_queue() in r8712_usb_dvobj_deinit(). Besides, in r871xu_dev_remove(), r8712_usb_dvobj_deinit() will be called by r871x_dev_unload() under condition `padapter->bup` and r8712_free_io_queue() is called by r8712_free_drv_sw(). However, r8712_usb_dvobj_deinit() does not rely on `padapter->bup` and calling r8712_free_io_queue() in r8712_free_drv_sw() is negative for better understading the code. So I move r8712_usb_dvobj_deinit() into r871xu_dev_remove(), and remove r8712_free_io_queue() from r8712_free_drv_sw().

2022-04-05random: opportunistically initialize on /dev/urandom readsJason A. Donenfeld1-0/+7
In 6f98a4bfee72 ("random: block in /dev/urandom"), we tried to make a successful try_to_generate_entropy() call *required* if the RNG was not already initialized. Unfortunately, weird architectures and old userspaces combined in TCG test harnesses, making that change still not realistic, so it was reverted in 0313bc278dac ("Revert "random: block in /dev/urandom""). However, rather than making a successful try_to_generate_entropy() call *required*, we can instead make it *best-effort*. If try_to_generate_entropy() fails, it fails, and nothing changes from the current behavior. If it succeeds, then /dev/urandom becomes safe to use for free. This way, we don't risk the regression potential that led to us reverting the required-try_to_generate_entropy() call before. Practically speaking, this means that at least on x86, /dev/urandom becomes safe. Probably other architectures with working cycle counters will also become safe. And architectures with slow or broken cycle counters at least won't be affected at all by this change. So it may not be the glorious "all things are unified!" change we were hoping for initially, but practically speaking, it makes a positive impact.

There are some uses of ternary operator where it explicitly sets true or false but the condition already evaluates to true or false. In this cases the ternary operator is redundant and can be removed.

2022-04-05staging: rtl8723bs: simplify control flowSevinj Aghayeva1-14/+4
Checkpatch issues "WARNING: else is not generally useful after a break or return" for the following code: while (1) { do_join_r = rtw_do_join(padapter); if (do_join_r == _SUCCESS) { break; } else { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } } We simplify this code in multiple steps. First, we remove do_join_r variable because it is only used right after it is assigned. Second, we remove the unnecessary else statement right after break: while (1) { if (rtw_do_join(padapter) == _SUCCESS) break; rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } Next, we move the call to rtw_do_join into the while test because the while will loop only until the call is successful: while (rtw_do_join(padapter) != _SUCCESS) { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) > 0) { continue; } else { rtw_indicate_disconnect(padapter); break; } } Finally, looking at the code above, it is clear that the code will break out of the loop if rtw_to_roam call is <= 0. Hence: while (rtw_do_join(padapter) != _SUCCESS) { rtw_dec_to_roam(padapter); if (rtw_to_roam(padapter) <= 0) { rtw_indicate_disconnect(padapter); break; } } Signed-off-by: Sevinj Aghayeva <sevinj.aghayeva@gmail.com> Link: https://lore.kernel.org/r/20220403224207.GA397480@euclid Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The function iterates an index from 0 to NUM_PMKID_CACHE and returns the first index for which the condition is true. If no such index is found, the function returns -1. Current code has a complex control flow that obfuscates this simple task. Replace it with a loop. Also, given the shortened function body, replace the long variable name psecuritypriv with a short variable name p.

2022-04-05kobject: kobj_type: remove default_attrsGreg Kroah-Hartman3-46/+0
Now that all in-kernel users of default_attrs for the kobj_type are gone and converted to properly use the default_groups pointer instead, it can be safely removed. There is one standard way to create sysfs files in a kobj_type, and not two like before, causing confusion as to which should be used. Cc: "Rafael J.

2022-04-05powerpc/pseries/vas: use default_groups in kobj_typeGreg Kroah-Hartman1-2/+4
There are currently 2 ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field. Move the pseries vas sysfs code to use default_groups field which has been the preferred way since aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type") so that we can soon get rid of the obsolete default_attrs field.
