fix: Avoid updating object tags on failed disks (#9819)

In the Current bug we were re-using the context
from previously granted lockers, this would
lead to lock timeouts for existing valid
read or write locks, leading to premature
timeout of locks.

This bug affects only local lockers in FS
or standalone erasure coded mode. This issue
is rather historical as well and was present
in lsync for some time but we were lucky to
not see it.

Similar changes are done in dsync as well
to keep the code more familiar

Fixes #9827

+For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow

+service iptables restart

-For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
-access to port 9000
-
-```sh
-iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
-service iptables restart

-Below command enables all incoming traffic to ports ranging from 9000 to 9010.

-## Pre-existing data
-When deployed on a single drive, MinIO server lets clients access any pre-existing data in the data directory. For example, if MinIO is started with the command  `minio server /mnt/data`, any pre-existing data in the `/mnt/data` directory would be accessible to the clients.
-
-The above statement is also valid for all gateway backends.

-MinIO Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure your server has started successfully.

 ## Test using MinIO Client `mc`
 `mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client [Quickstart Guide](https://docs.min.io/docs/minio-client-quickstart-guide) for further instructions.
 
-# Upgrading MinIO
+## Pre-existing data
-MinIO server supports rolling upgrades, i.e. you can update one MinIO instance at a time in a distributed cluster. This allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However, we recommend all our users to use [`mc admin update`](https://docs.min.io/docs/minio-admin-complete-guide.html#update) from the client. This will update all the nodes in the cluster simultaneously and restart them, as shown in the following command from the MinIO client (mc):

-> NOTE: some releases might not allow rolling upgrades, this is always called out in the release notes and it is generally advised to read release notes before upgrading. In such a situation `mc admin update` is the recommended upgrading mechanism to upgrade all servers at once.
+**Important things to remember during upgrades**:
-
-## Important things to remember during MinIO upgrades
 
 - `mc admin update` will only work if the user running MinIO has write access to the parent directory where the binary is located, for example if the current binary is at `/usr/local/bin/minio`, you would need write access to `/usr/local/bin`.
-- `mc admin update` updates and restarts all servers simultaneously, applications would retry and continue their respective operations upon upgrade.
+- In the case of federated setups `mc admin update` should be run against each cluster individually. Avoid updating `mc` until all clusters have been updated.
-- `mc admin update` is disabled in kubernetes/container environments, container environments provide their own mechanisms to rollout of updates.
+- If you are updating the server it is always recommended (unless explicitly mentioned in MinIO server release notes), to update `mc` once all the servers have been upgraded using `mc update`.
-- In the case of federated setups `mc admin update` should be run against each cluster individually. Avoid updating `mc` to any new releases until all clusters have been successfully updated.
+- `mc admin update` is disabled in docker/container environments, container environments provide their own mechanisms for updating running containers.
-- If using `kes` as KMS with MinIO, just replace the binary and restart `kes` more information about `kes` can be found [here](https://github.com/minio/kes/wiki)
+- If you are using Vault as KMS with MinIO, ensure you have followed the Vault upgrade procedure outlined here: https://www.vaultproject.io/docs/upgrading/index.html
-- If using Vault as KMS with MinIO, ensure you have followed the Vault upgrade procedure outlined here: https://www.vaultproject.io/docs/upgrading/index.html
+- If you are using etcd with MinIO for the federation, ensure you have followed the etcd upgrade procedure outlined here: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md
-- If using etcd with MinIO for the federation, ensure you have followed the etcd upgrade procedure outlined here: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md

-## 升级 MinIO
-MinIO 服务端支持滚动升级, 也就是说你可以一次更新分布式集群中的一个MinIO实例。 这样可以在不停机的情况下进行升级。可以通过将二进制文件替换为最新版本并以滚动方式重新启动所有服务器来手动完成升级。但是, 我们建议所有用户从客户端使用 [`mc admin update`](https://docs.min.io/docs/minio-admin-complete-guide.html#update) 命令升级。 这将同时更新集群中的所有节点并重新启动它们, 如下命令所示:
-
-```
-mc admin update <minio alias, e.g., myminio>
-```
-
-> 注意: 有些发行版可能不允许滚动升级，这通常在发行说明中提到，所以建议在升级之前阅读发行说明。在这种情况下，建议使用`mc admin update`升级机制来一次升级所有服务器。
-
-### MinIO升级时要记住的重要事项
-
-- `mc admin update` 命令仅当运行MinIO的用户对二进制文件所在的父目录具有写权限时才工作, 比如当前二进制文件位于`/usr/local/bin/minio`, 你需要具备`/usr/local/bin`目录的写权限.
-- `mc admin update` 命令同时更新并重新启动所有服务器，应用程序将在升级后重试并继续各自的操作。
-- `mc admin update` 命令在 kubernetes/container 环境下是不能用的, 容器环境提供了它自己的更新机制来更新。
-- 对于联盟部署模式，应分别针对每个群集运行`mc admin update`。 在成功更新所有群集之前，不要将`mc`更新为任何新版本。
-- 如果将`kes`用作MinIO的KMS，只需替换二进制文件并重新启动`kes`，可以在 [这里](https://github.com/minio/kes/wiki) 找到有关`kes`的更多信息。
-- 如果将Vault作为MinIO的KMS，请确保已遵循如下Vault升级过程的概述：https://www.vaultproject.io/docs/upgrading/index.html
-- 如果将MinIO与etcd配合使用, 请确保已遵循如下etcd升级过程的概述: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md

-## Vulnerability Management Policy
-
-This document formally describes the process of addressing and managing a
-reported vulnerability that has been found in the MinIO server code base,
-any directly connected ecosystem component or a direct / indirect dependency
-of the code base.
-
-### Scope
-
-The vulnerability management policy described in this document covers the
-process of investigating, assessing and resolving a vulnerability report
-opened by a MinIO employee or an external third party.
-
-Therefore, it lists pre-conditions and actions that should be performed to
-resolve and fix a reported vulnerability.
-
-### Vulnerability Management Process
-
-The vulnerability management process requires that the vulnerability report
-contains the following information:
-
- - The project / component that contains the reported vulnerability.
- - A description of the vulnerability. In particular, the type of the
-   reported vulnerability and how it might be exploited. Alternatively,
-   a well-established vulnerability identifier, e.g. CVE number, can be
-   used instead.
-
-Based on the description mentioned above, a MinIO engineer or security team
-member investigates:
-
- - Whether the reported vulnerability exists.
- - The conditions that are required such that the vulnerability can be exploited.
- - The steps required to fix the vulnerability.
-
-In general, if the vulnerability exists in one of the MinIO code bases
-itself - not in a code dependency - then MinIO will, if possible, fix
-the vulnerability or implement reasonable countermeasures such that the
-vulnerability cannot be exploited anymore.
