[PATCH] [4.19.y] net/sched: move NULL ptr check to qdisc_put() too

by Diederik de Haas

In commit 92833e8b5db6c209e9311ac8c6a44d3bf1856659 titled "net: sched: rename qdisc_destroy() to qdisc_put()" part of the functionality of qdisc_destroy() was moved into a (for linux-4.19.y) new function qdisk_put(), and the previous calls to qdisc_destroy() were changed to qdisk_put(). This made it similar to f.e. 5.10.y and current master. There was one part of qdisc_destroy() not moved over to qdisc_put() and that was the check for a NULL pointer, causing oopses. (See upstream commit: 6efb971ba8edfbd80b666f29de12882852f095ae) This patch fixes that.

[PATCH stable-5.15] io_uring: fix not locked access to fixed buf table

by Pavel Begunkov

[ upstream commit 05b538c1765f8d14a71ccf5f85258dcbeaf189f7 ] We can look inside the fixed buffer table only while holding ->uring_lock, however in some cases we don't do the right async prep for IORING_OP_{WRITE,READ}_FIXED ending up with NULL req->imu forcing making an io-wq worker to try to resolve the fixed buffer without proper locking. Move req->imu setup into early req init paths, i.e. io_prep_rw(), which is called unconditionally for rw requests and under uring_lock.

[PATCH stable 0/4] net: mscc: ocelot: allow unregistered IP multicast flooding

by Vladimir Oltean

This series contains 4 patches (1 for each stable branch: 4.19, 5.4, 5.10 and 5.15) which fix 2 variations of the same problem: - Between kernels 4.18 and 5.12, IP multicast flooding on ocelot ports is completely broken, both for autonomous forwarding and for local CPU termination. The patches for 4.19 and for 5.10 fix this. - Between kernels 5.12 and 5.18, the flooding problem has been fixed for autonomously forwarded IP multicast flows via a new feature commit which cannot be backported, but still remains broken for local CPU termination. The patch for 5.15 fixes this. After kernel 5.18, the CPU flooding problem has also been fixed via a new feature commit which also cannot be backported. So in the current "net" tree, both kinds of IP multicast flooding work properly, and this is the reason why these patches target just the "stable" trees.

[PATCH stable 4.9] fdt: Update CRC check for rng-seed

by Florian Fainelli

From: Hsin-Yi Wang <hsinyi(a)chromium.org> commit dd753d961c4844a39f947be115b3d81e10376ee5 upstream Commit 428826f5358c ("fdt: add support for rng-seed") moves of_fdt_crc32 from early_init_dt_verify() to early_init_dt_scan() since early_init_dt_scan_chosen() may modify fdt to erase rng-seed. However, arm and some other arch won't call early_init_dt_scan(), they call early_init_dt_verify() then early_init_dt_scan_nodes(). Restore of_fdt_crc32 to early_init_dt_verify() then update it in early_init_dt_scan_chosen() if fdt if updated.

[PATCH v4.9] kexec_file: drop weak attribute from arch_kexec_apply_relocations[_add]

by Naveen N. Rao

commit 3e35142ef99fe6b4fe5d834ad43ee13cca10a2dc upstream. Since commit d1bcae833b32f1 ("ELF: Don't generate unused section symbols") [1], binutils (v2.36+) started dropping section symbols that it thought were unused. This isn't an issue in general, but with kexec_file.c, gcc is placing kexec_arch_apply_relocations[_add] into a separate .text.unlikely section and the section symbol ".text.unlikely" is being dropped. Due to this, recordmcount is unable to find a non-weak symbol in .text.unlikely to generate a relocation record against. Address this by dropping the weak attribute from these functions. Instead, follow the existing pattern of having architectures #define the name of the function they want to override in their headers.

[PATCH stable 4.19] swiotlb: skip swiotlb_bounce when orig_addr is zero

by Liu Shixin

After patch ddbd89deb7d3 ("swiotlb: fix info leak with DMA_FROM_DEVICE"), swiotlb_bounce will be called in swiotlb_tbl_map_single unconditionally. This requires that the physical address must be valid, which is not always true on stable-4.19 or earlier version. On stable-4.19, swiotlb_alloc_buffer will call swiotlb_tbl_map_single with orig_addr equal to zero, which cause such a panic: Unable to handle kernel paging request at virtual address ffffb77a40000000 ... pc : __memcpy+0x100/0x180 lr : swiotlb_bounce+0x74/0x88 ...

[PATCH] ARM: alignment: advance IT state after emulating Thumb instruction

by Ard Biesheuvel

After emulating a misaligned load or store issued in Thumb mode, we have to advance the IT state by hand, or it will get out of sync with the actual instruction stream, which means we'll end up applying the wrong condition code to subsequent instructions. This might corrupt the program state rather catastrophically. So borrow the it_advance() helper from the probing code, and use it on CPSR if the emulated instruction is Thumb.

Gooday my beloved,

Gooday dear friend, I sent this mail praying it will get to you in a good condition of health, since I myself are in a very critical health condition in which I sleep every night without knowing if I may be alive to see the next day. I bring peace and love to you. It is by the grace of God, I had no choice than to do what is lawful and right in the sight of God for eternal life and in the sight of man, for witness of God’s mercy and glory upon my life,I am Mrs,Grayson Jackie,a widow.I am suffering from a long time brain tumor, It has defiled all forms of medical treatment, and right now I have about a few months to leave, according to medical experts.The situation has gotten complicated recently with my inability to hear proper, am communicating with you with the help of the chief nurse herein the hospital, from all indication my conditions is really deteriorating and it is quite obvious that, according to my doctors they have advised me that I may not live too long, Because this illness has gotten to a very bad stage. I plead that you will not expose or betray this trust and confidence that I am about to repose on you for the mutual benefit of the orphans and the less privilege. I have some funds I inherited from my late husband, the sum of ($11,500,000.00 Dollars).Having known my condition, I decided to donate this fund to you believing that you will utilize it the way i am going to instruct herein. I need you to assist me and reclaim this money and use it for Charity works, for orphanages and gives justice and help to the poor, needy and widows says The Lord." Jeremiah 22:15-16.“ and also build schools for less privilege that will be named after my late husband if possible and to promote the word of God and the effort that the house of God is maintained. I do not want a situation where this money will be used in an ungodly manner. That's why I'm taking this decision. I'm not afraid of death, so I know where I'm going. I accept this decision because I do not have any child who will inherit this money after I die. Please I want your sincerely and urgent answer to know if you will be able to execute this project for the glory of God, and I will give you more information on how the fund will be transferred to your bank account. May the grace, peace, love and the truth in the Word of God be with you and all those that you love and care for. I'm waiting for your immediate reply, Regards Mrs,Grayson Jackie, Writting From the hospital, May God Bless you,
